JB Workaround CalDAV-Sync

This is just a workaround app for a bug in Android 4. 1 See. Com/p/android/issues/detail? Id=34880 for details. Info for Samsung users: at present you'll need this app too, see. Under Android 4. 4. 2 it's recommended to install this app as well. There is a new issue in Android that causes accounts to be removed during an app update, see.
