Graphics: Added font rendering functions Graphics::DrawText and Graphics::StringImage.

FileHandler: Added support for wav
Audio: Added support to play back a sound with XAudio2. We can't delete sounds until we make our own system to keep track of available voices.
LoginScreen scene: Upped framerate from 15fps to tickless, and added new logic to clone the scrolling text at the bottom. All of it.
