Feat update robotium

Hello!
This pull request updates robotium to 5.0.1
This included changing classpaths and I had to fix some dependencies etc.

I also fixed a few bugs:
* Fixes a possible API access bug in ClearAppData
* The test server has also been updated to require API 19 for compiling.
* Tried to fix swipe gesture as suggested [here](https://code.google.com/p/robotium/issues/detail?id=402&colspec=ID%20Type%20Stars%20Status%20Priority%20Milestone%20Owner%20Summary) but a colleague mentioned this as still being somewhat broken. I guess we have to work upstream for this to work reliable.

I forgot to turn off auto formatting in eclipse, hence why some files have quite a lot of formatting changes.
I can **not** confirm if this is 100% working because I don't have a test suite for calabash, but I have run old tests on with a project and they work as intended.
