Misc fixes

- NavigationHandlerFragment: fixed tacking of navigation item click to
handle what fragment is selected
- ImageCacheUtils: fixed TAG constant
- PhotoUtils: added generatePhotoTitle method
- NewPhotoObserver: fixed determining of mime type by extension in the
getMimeType. Extension should be in lower case, otherwise null value is
received
- UploaderService: added title generating code to the handleIntent
method (currently commented)
- HorizontalListView: fixed fillListRight method to do not remove most
left view in some cases
- ImageUtils: added new constants for mime datetime
- ImageUtils: added new methods getExifDateTime (2 variations)
