add support for ActionBarCompat (Issue #74) and fix a few other issues

- added Android Support Library/ActionBarCompat CameraFragment
- added demo-support to support it
- fixed landscape lock double click bug on rotation in demo-support
- changed saveImage() to return path to image
- updated SDK versions to latest
- add setCameraView to compatibility CameraFragments (it was only in the main CameraFragment)
- fixed deprecated usage of getOrientation()
- log an error if it couldn't create the photo directory on External SD card (which is required for this library...it should have a method to set the default destination directory)
