Python-nightscout

This is a point release to upgrade some of the dependencies, to make it easier for uses to get the latest version of all the packages libraries. There are no core Nightscout code changes in this releases.

This is a bug fix / improvement release in the 0.12 series.

**Changes:**

* Most Javascript in the site is now transpiled (yes this is highly technical) to be compatible with older devices such as iPads running iOS 9, so devices that haven’t worked correctly with release 0.12 probably work after upgrading to 0.12.4
* Medtronic Guardian Connect Plugin has been updated to be compatible with US users
* Clock views now show the X to close on load, which then hides itself until screen is clicked
* Several bug fixes to the clock views
* Daily reports don’t show estimated insulin values for carbs due to potential confusion over this referring to dosed insulin
* Profile conversion warnings were disabled
* Fixed a plugin setting rendering bug introduced in the 0.12.3
* German and Russian language updates
* Mmol unit conversion fixes
* Several small documentation improvements
* Fixed an issue causing a client crash on first start of a new site
* Temporary Target Cancel event bug introduced in the previous release has been fixed

**Random tidbit: at the time of release, Nightscout is the 10th most forked project in the entire Github!**

This is a bug fix / improvement point release of Nightscout Jellybean

**New features**

* Adds option to colorize the OpenAPS prediction lines, along with a new mechanism for plugins to expose their extended settings to the client UI, so this setting can be switched on and off in the client
* CarePortal now validates Temporary Target values and prevents saving entries with broken data

**Changes**

* Lowers the Node version requirement to allow Azure deploys. Azure deploys are still likely to fail on free Azure tiers due to running out of hosting resources to run the site. Microsoft is looking into this and hoping to provide us a solution to hosting Nightscout in Azure, but for now if you want to upgrade to this release, you will need to use a paid Azure tier or an alternate hosting solution like Heroku (instructions on how to migrate to Heroku are to be found at nightscout.info)
* Updated documentation regarding Azure and above mentioned configuration
* **OpenAPS 0.6 users** OpenAPS 0.6 has issues with date comparison that cause the Nightscout treatment synchronization to fail for users in time zones with the relative time earlier to UTC (UTC minus something). This release adds a workaround to the system that converts dates back to the originating form in the REST API, causing the OpenAPS date comparison logic to work as expected. You can enable this workaround by setting DE_NORMALIZE_DATES=true in Heroku / Azure.* Fixes the button positioning the toolbar
* The clock view close X button is now controlled by a parameter in the URL and a setting. If you want to bookmark a clock view without the X but have the X appear when opening the view from the navigation, open the clock view from Nightscout navigation and remove the `showClockClosebutton=true` parameter from the page address before adding the bookmark. To have the X never appear, set `SHOW_CLOCK_CLOSEBUTTON` to `false` in the server settings.
* Latest Stop Sensor event from last 32 days is now loaded to fix some plugin issues for users who have a sensor that was started and stopped recently but more than 2 days ago

**Developers**

* Allow Node 12 in the node version checks
* Swagger REST API documentation how works over /api-docs and developer docs in CONTRIBUTING.md have been updated

Another small but important fix: adds X close buttons to all views on the site, to help unstuck iOS users who've added the site to springboard, so they don't have to restart the phone to get back to the graph view

Bug fix release: the 0.12.0 release had an issue with loading the clock view javascript bundle, which was fixed in this release


**Overview**

The release focuses improving the data management and packaging of Nightscout, to both make it load faster and consume less resources on the client, but also to fix data related issues. Based on testing, the release resolves many issues related to data, such as site loading slowly or the admin section showing treatments in the future.

**READ THIS:** The Nightscout REST API now normalizes dates in the data to the UTC time zone. This might cause some data loading to behave unexpectedly for n hours after updating the site (where n is the number of hours between your local time and UTC). If you're using systems that syncronizes data both ways with Nightscout (such as a DIY artificial pancreas), please keep a close eye to how everything is behaving after you upgrade.

While installing, please sanity check the following:

* Check you have the DISPLAY_UNITS setting in Heroku or Azure, and that it's set to either _mmol_ or _mg/dl_
* In the Profile Editor, double check the profile is fully filled and matches the actual profile

**Notable new features**

* Guardian Connect now supports the EU servers (set MMCONNECT_SERVER=EU in site settings, among other parameters)

**Notable changes**

* Random metrics: 12299 new lines of code, with 6692 old lines gone
* The site now loads less data on start, with up to around 50% less data needed for people using a DIY artificial pancreas
* Related to the data loading changes, battery, cannula, sensor age now support up to 31 day old entries
* You can now log protein and fat intake for meal treatments and see the aggregate records in daily reports
* Speech: Pressing the button to enable sounds now also enables speech on mobile devices
* Guardian Connect now supports the EU servers (set MMCONNECT_SERVER=EU in site settings, among other parameters)
* Nightscout now visualizes Guardian users’ trend arrows using the one to three arrow format for consistency with Medtronic CGM systems
* REST API fixes to bugs introduced in the previous release
* Fixes an issue where the latest iOS caused a stale data alarm every time, when Nightscout had been added as a Home Screen web app
* Javascript packaging has been improved, so the site should both load faster and require less memory to run
* Layout fixes for setups with a lot of features enabled
* Glucose distribution report was showing slightly elevated variability for users with noisy CGM records
* Plugin code was improved to reduce issues when a single plugin is misbehaving
* Many dependencies were updated to newer versions with no know security issues
* Many language updates and fixes

**Developers**

* The REST API now users Moment.js to parse dates and normalize the date to UTC. If the date had a time zone defined in the object, the resulting new date will be in UTC and a new _utcOffset_ field will be added to the data, which defines the time zone delta from UTC in minutes (positive numbers indicate zones ahead of UTC)
* The clock face code was completely refactored
* ESLint is now happy with the site (and .eslintrc is committed to the repository)
* Developers should check CONTRIBUTING.md for changes in how the site is now run in dev mode and how to run the site to get automatic reload on code changes. Javascript packaging now uses the webpack dev mode along with nodemon, so when running in dev mode, all changes are deployed when you save changes in your editor. The site also runs eslint in the packaging mode; please check any reported errors and fix them before PRing changes.
* The repository now includes .eslintrc and .jsbeautifyrc files; using VSCode for editing with those plugins is recommended
