Fixed the state for the playlists menu item to show the currently playing playlist.

Fixed the state for the playlists menu item to show the currently playing playlist.
Added a new hotkey to toggle if a song should appear in shuffle.
Slightly modified the table view in the hot keys tab of the preferences.
I still have to make a status window for shufflability state.
Changed multiple instances of iTunesRemote using int32Value to typeCodeValue, which will hopefully reduce breakage in the future.
