Implement ActionBar using AppCompat in cgeo

This a first version of an ActionBar implementation with following properties:

- The application should be usuable (there still might be bugs left from the conversation to Action)
  - Provides a more modern feeling on all devices
  - gets rid of the "dots of shame" on Android 3.0+ devices
- The Maps classes MUST inherit from Activity instead of ActionBarActivity. There these classes use the old ActionBar on Android 2.3 devices and the real ActionBar on 3.0+
   - This can be fixed when cgeo is ported to Google Maps API v2.0 API which usesFragment
- The Dialog classes (CachePopup and WaypointPopup) have been converted to DialogFragments
  - The AppCombat themes provide no Theme.Dialog theme
  - this will later ease using these Fragment in other Activities
  - Use an almost empty activity which just shows the DialogFragment
  - Use the 'old' ActionBar but which overflow menu button to fit into Holo Design Style
  - Using a real ActionBar for Dialogs is not really support by Android and trying to force the frame into showing an Actionbar on a dialog leeds to strange bugs/effects
- Most of the icon are still the Android 2.3 Menu Icon. These need to be replaced with Holo Style Icons
- for most menu icon the ifRoom and/or withText attributes should be reviewed and set
- The ActionBar of the main Activity is transparent. This is more or less by accident but looks good
- Review Up Action of activities. Is going back to Main Activity alwasy the semantically right thing to do?
- Shortpress/Longpress on the Actionbars Compass Icon for primary/secondary Navigation clashes the normal ActionBar behaviour of long pressing to show the text of the action
