Large changes in the seperation of backend and google handler

- backend now takes care of all the recoloring, and communication with database
- google handler takes care of the entire communication with google
- colors selected on the front-end are now translated to the watch

- Calendars in the database now directly save the color the user has set
- only if the event has a different color than the calendar (event color from google is not 0)
  is the event color from google used.
- No more passing around of google color ids, hex colors all the way
