New features

Refactor some of the UI to make it easier to maintain.
Added feature to force device to search for the stronget AP.
Fixed the issue with gyro not working on c3 board (had to disable LED since it collides with gyro).
Removed BLE GravityMon Service option since this is not really performing well.
Added WIFI Direct Connect option with GravityMon Gateway, I hope this will help with wifi connection issues in my steel fermenter and force a connect to the designated AP. Wifi Direct will send the data via http
to the Gateway and then forward this to the correct endpoint.
Added line breaks to format editor for easier editing
Added check if device is responding and notify user when there is an issue
Redesign of user interface using VueJS as the base (UI moved to separate github project mp-se/gravitymon-ui)
Added authorization for API access (currently basic and not really secure)
Redesigned REST-API to function better with VueJS
Updated documentation to match new version (Still some more work needed)
Updated API tests to match new API (Still some more work needed)
Moved WIFI configuration to the main application (Removed WiFi Manager)
Added additional BLE options for ESP32 builds

Issues adressed

Temp sensor not always beeing detected, Switch to OnewireNG which seams to fix the problem
Fixed led indicator when going into wifi mode
Turning off led when going to sleep mode or doing reset
