Fixing Eclipse project properties and ant build

Hello Jan,
Could you please verify my fix for issue #9 by 
- opening the android lib project in eclipse and seeing there are no build errors
- running the ant build script from the shell, verifying the lib gets properly generated and installed, and the framework starts properly
I tested this on OpenSUSE Linux 12.2 and MacOS 10.8.5. Let me know if there are any problems!
