Garry's Mod JukeBox - YouTube Music Player

1. Chat messages should now work on EVERY gamemode.
2. [REQUEST] Button added for Managers to add a song straight to the all songs list rather than it needing accepting as a request.
3. Removed debug print messages (I have no idea if these actually ended up in the last update but they're not in this one.)

There have been no changes to the shared_settings.lua file, so you don't need to overwrite your version of the file.
