Given Pandora search result it's own file, and finished code for enabling/disabling the create button
Added a special method that returns the result for the row in the Station Creator
Station creation now works, but is not exposed
Forgot to set stationController to nil after releasing it
stationController does not get released
Corrected PandoraConnection method -createStation to add the station to the correct objects.
AppDelegate and PandoraConnection now share the stationList object
Added description methods to PandoraConnection, Station, Song, and SearchResult
