Added settings to configure default album sort order and default search ...

"Added settings to configure default album sort order and default search type"

I got fed up with having to switch to album view all the time and tried to implement an option in the settings to be able to change the default values for the selectedSubsonicAlbumSort and SearchType drop down lists.

I might have missed it but is there a function to share data between controllers other than accessing the controller via the globals variable? Or is that the preferred way perhaps?

This is the first time I'm committing something to someone else's repository so please tell me if I've done something wrong.
