Add Audio Loader as submodule

[RomanMiray]

Audio Loader is a plugin that allows one to set custom ui sounds and background music for STEAM BIG PICTURE MODE (background music is not implemented yet). I've already installed a few basic themes with sounds of xbox, playstation and switch.

(Before that I never used Lua and this is my first attempt to create my own plugin, so sorry if the code isn't ideal, i'm ready to fix it anyway)

Checkout the new plugin docs, I've added some more documentation about what modules Millennium ships. In your case, the fs module will be incredibly useful. Once you move your code to use fs, we will begin the approval process!

Thank you very much, gonna do it. But background music feature seems to me really hard to implement. Do you have an idea how to do this? I'm desperately trying to implement it but without any results.
