Garry's Mod JukeBox - YouTube Music Player

1. Prevented abuse of net message spam causing clients to be kicked.
2. Added warning to ADMIN - Requests page about the maximum size of All Songs list.
3. Added language phrases: #REQUESTS_Warning, #REQUESTS_WarningPopup, and #POPUP_Warning.
4. Added compression to the transmission of the All Songs list
5. Added MySQL support to IdleSongs list (cannot be converted, you will need to manually check them again).
6. More changes from v1.9.4 to attempt to fix file read problems on some servers.

I'll be looking into a more permanent solution for the net message limit when I have time. Hopefully, this will help people avoid the problem until then.

There have been changes to the shared_language.lua file, so be sure to copy over and update your languages carefully.
