Garry's Mod JukeBox - YouTube Music Player

This update adds support for SH Pointshop. As I don't have access to the addon, I have marked this update as a beta, as I have been unable to test it. You do not need to update if you don't need this feature.

1. Added SH Pointshop Support (BETA)
2. Added JukeBox.Settings.UseSHPointshop (default false)
3. Added language phrase #ALLSONGS_CostSHPS
4. Added YouTube ToS and Google Privacy Policy messages to Options page
5. Added 6 new language phrases under the ABOUT AREA section that refer to this section
6. In order to comply with YouTube's API terms of service and continue using their API, they have requested that I include these links within the addon. Without them, I would not be allowed to use the API.

There have been changes to the shared_settings.lua and shared_language.lua files, so be sure to copy over your settings carefully.
