Add some DCOP functions to PlayerManager.
* Get volume. * Find out if a song is playing/paused/stopped. * Get metadata on the currently playing song, including filename. Fix spacing problems I introduced in my last commit (plus I just now triple-checked ;-) ). Once the new Collection Manager is in place I'll do the rest of the DCOP features and close the bugs.
