Support For Api 8

I know you rejected the previous pull request, but check this out. I fixed most of the issues. Very minor problems remained with drag&drop. Try the example app on an emulator and see for yourself. 10% of potential customers is a lot for applications with million or more installs. It would be good to support API >= 8.

- Add support for API >= 8 for the example app with AppCompat library. 
- Updated Drag&Drop code to use NineOldAndroids. Fixed most of the problems for API < 14. The only problem left is that the mobileView does not become invisible...
- Fixed a problem which prevented running the app on an Emulator without Google Play Store.
- Fixed issue #254 (looks like recycling was still a problem on >= 14 but much less visible than < 14)
