working dummy-example for AccountManager
somehow I made oauth with accountmanager work a bit :)
cleanup and converted FriendGroupOverview to successfully use AccountManager
some more cleanup
sync adapter does something...
doing some syncing of the groups... auth still pretty brittle...
TAG for debugging statements in SyncAdapter
playing with UI and notifications...
Merge branch 'accountManager'

Conflicts:
	cachewise-app/src/main/java/com/cachewise/app/FriendGroupOverview.java
example buggy but somewhat complete: view shows groups from db, button requests new sync, SyncAdapter syncs and writes notifications
