Script fragment

ScriptFragment implemented with smart brick selection, layout adaptions, animation, deleteActionMode

Jenkins testrun:

There is one strange WindowManager$BadTokenException which crashes with InstrumentationFault in SetLookBrickTest (testDelete/testRename) when clicking on the spinner after changing fragments (see http://catrobatgw.ist.tugraz.at:8080/job/Catroid-custom-branch-test/417/console). This is only an issue on Android 2.x. I'd look at this after the release candidate.

Functionality fully implemented.
TODO for next iteration:
- Insert new drawables from design team when available
--> this should also fix the issue of correct padding and greying of bricks
- maybe fix the above mentioned error
