Magicblue

* Time schedules thanks to StevenLooman ! (43)
* Update to bluepy 1.1.4
* API documentation on http://magicblue.readthedocs.io/en/latest/

* Improved compatibility with v7
* `magicblueshell` multi-bulbs mode
* Update bluepy to `1.1.2`

Effects are now implemented thanks to StevenLooman. Support for this has been added to magicblueshell.

Also fixed a crash on interactive mode.

- Methods to read / write characteristics directly from the bulb (name, datetime, device info)
- Add a `test_connection` method to the API to test if connection is still alive
- There should not be other incompatibilities with future versions of the bulb as we now get the handle from characteristics

Thanks to [StevenLooman](https://github.com/StevenLooman) for these great changes !

- Compatibility with V9 bulbs (use "--bulb-version 9")
- Connect to a device faster by entering the ID shown in the list when using "list_devices" command

**Migration to BluePy library**
Gatt library has been totally removed to instead use BluePy, which results in stability / compatibility improvements.
