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
Merge pull request #1025 from Catrobat/emulatorTest

refactor tests for new emulators
refactor local versionName

- with a leading 'v' in versionName (e.g. v0.9.8-96-g082c2c5 master)
it is not possible to execute uploadwebtests and upload projects to
pocketcode.org with a local build.
- updated projectVersion to be consistent for jenkins and local builds
update sdkmanager plugin
