Fixed numerous rendering bugs on AMD and possibly Intel GPUs (music not visualizing correctly, laser weapon showing huge red bloom, antialiased lines not rendering correctly).

UI bugfixes for large playlists.

Some fixes for enemies with more than 1 gun attached to them.

Better OpenGL error logging if running the game with --debug=1

Some newer unfinished content available with --debug=1

Please let me know if anything broke that worked before; I have a limited set of hardware I can use for testing. I try to not break anything on hardware I don't have, but sometimes it happens.
