Added logic to addNewAlbum_backend to add the new simpleAlbumData object
to the end of the _albumsToReturn observableCollection so that the GUI
updates. Tested and verified this works. It even does the cool flip in
animation after the new album is created. Also added comments noting where
on previous testing for last commit unhandled exceptions were raised. I
didn't want to handle them yet as I want to converse will Bill about it.
