quickfix for uitests

- no context available; currently hardcoded program names
  needed for cleaning up pocket code directory
- BroadcastBricksTest caused IndexOutOfBoundsExceptions -
  starting from MainMenuActivity should work
- modified SettingsActivityTest; testOrientation tested
  MainMenuActivty instead of SettingsActivity
- WebView methods have to be run on the UI Thread -
  at least our new emulator (api18) complained
- move randomly failing testcases to Devicetest
- delete SharedPreferences projectname - could cause
  Nullpointers on later tests
