Merge pull request #13 from foreverguest/master

Implement search
Added some sanity to the filters.

* Album filter will order songs by track.
* Artist filter sorts by album then by track.
* Album listing is sorted alphabetically.

Obviously this could be improved and more flexible, but
I feel like this at least "sane" compared to nothing.
