Allow to pick favourite stations, show them at top of the list of stations

It's all in the title.
It would be useful to be able to just open the app and see if your local station(s) have free bikes (or spaces).

Usecase: get up in the morning, want to cycle to your location of choice, need to know which local station has free bikes.

Hope this suggestion helps :)

I'm working on it ;) I had to change a lot of code, it's usable but not perfect yet.
