Adding a general information endpoint for getting the total number of tracks and the total duration of the tracks
Fixing some shit to make this compatible with SQL Azure.
Basically it amounts to removing a table that wasn't being used but didn't have a primary key. And removing a custom error code since those aren't supported.
Not sure if the fix will cause issues, but since I was never catching the custom error, I doubt it'll cause any NEW issues. lol.
Slight bug fix to handle the change from a namevaluecollection to dictionary for the get params.
I'm not thrilled about bringing in the LINQ dependency here.
