Title: Add ability for the activity to accept NSURLs

When I need to share an audio file, most of the time I have its NSURL. And I don't want to pass both NSURL and AVURLAsset to the UIActivityViewController, since some UIActivities accept both NSURL and AVURLAsset.

So I made the NBSoundCloudActivity to accept NSURL and check if belongs to audio file.
