Spoolman

Frontend
* **Added a new Locations page** that shows an overview of your spools and where they are. You can move Spools around, add new locations, etc, from here.
* add archive/un archive button to spool view page by TomW1605 in https://github.com/Donkie/Spoolman/pull/517
* add external id to filament and vendor edit pages by TomW1605 in https://github.com/Donkie/Spoolman/pull/518
* Fixed not being able to clear the price field on filaments and spools.

Backend
* Update gitattributes to preserve LF line endings on the `.env.example` file by uro666 in https://github.com/Donkie/Spoolman/pull/497
* Added REST API to export spools, filaments or vendors as CSV or JSON. No frontend made for this yet. See the API docs on how to use this.
* Server logs now have a more consistent format for the different logging sources. This also fixes so the LOGGING_LEVEL variable is respected.
* Fixed vendor with spool weight 0 not being allowed in response structure, causing errors if you added a vendor with spool weight 0.

Minor update this time around. This update most importantly fixes an issue where spool usage would be many times greater than what it should be in some situations.

Frontend
* Added double curly braces to printing dialog template which lets you add a prefix to fields that only shows if the field is set. By TomW1605 in https://github.com/Donkie/Spoolman/pull/446
* Improved contrast for the new spool icon if the color is similar to the background. By teoteo in https://github.com/Donkie/Spoolman/pull/458
* Add option to use full URL in QR codes instead of web+spoolman: prefix. By samturner3 in https://github.com/Donkie/Spoolman/pull/461

Backend
* Fixed issue where spool usage updates from plugins would partially fail because Spoolman failed to send websocket updates to disconnected clients. The spool usage was actually committed to the database correctly, but Moonraker interpreted it as a failure, so it kept retrying the usage, causing the spool usage to skyrocket.

Frontend
* Fixed multi color picker in create filament page not working
* Fixed importing multi color filaments in create filament page and create spool page

**Full Changelog**: https://github.com/Donkie/Spoolman/compare/v0.19.0...v0.19.1

Major changes
* Added support for multi-color filaments.
* Many label printing upgrades.
* Dialog to add/subtract filament from a spool.

**Note**: Due to the new label printing preset system in this update, all of your label printing settings will be reset. Note down your settings before updating so you can re-apply them after the update.

Remember to clear your browser cache to receive all the frontend updates. Ctrl + F5 in the Spoolman page.

Frontend
* Added frontend support for the new multi-color filaments.
* Got rid of the spool color icon in the filament column and now uses a more minimalistic box instead. This was necessary since showing multi-color filaments using the spool icon wasn't really feasible.
* Column filters now perform exact matches, this prevents seeing e.g. "PLA+" filaments when filtering for just "PLA" filaments.
* Updated text alignment and number precision of various list columns, by tzahari
* Added button in spool list page to add/subtract filament from the spool either by weight or length.
* Fixed not being able to set spool weight to 0.
* Fixed showing wrong spool price if it was overridden to 0 in the spool.
* Fixed item cloning not handling extra fields correctly.
* Label printing upgrades:
* Dialog is now its own page instead of being a modal, this improves the UX quite a lot.
* Added button in spool show page to take you to printing a label for that spool directly.
* Added backend-stored preset system. Previously all the settings were stored in your browser, but now they're stored in the Spoolman backend database instead, to let you share between different computers, and to reduce the risk of them disappearing. **Settings from the old system will not be carried over automatically.**
* Added new text-based template field where you can customize the content and layout of the text on the label. This also opens up the ability for your to print the values of your extra fields.
* Added "Save as Image" button which downloads all displayed labels as .png images.
* Added ability to specify item copies in label printing dialog, if you want multiple labels per spool.
* Added ability to hide the QR code entirely on the label.

Backend
* Updated database schemas and backend to support multi-color filaments. To make it backwards compatible, this is represented as a new field called `multi_color_hexes` on the filament object. See the REST API documentation for more details.
* Updated Pydantic and FastAPI to v2.
* Changed docker base image to Python 3.12 Debian Bookworm, previously it used Python 3.11 Alpine.
* Added backend support to perform exact matches, surround a search term with quotes to match exactly.
