Several improvements in UI (better colors for night mode, added icons).

Better handling of startup (login activity would reset if put in the background).
Allow use of schemeless hostname for login.
Destroy main activity and clear cache on logout.
Change of endpoint for favorites retrieval for one with much better performance.
