Audio: Replace SFML solution by using OpenAL directly
This is a major change in the Audio module that comes with many changes throughout the codebase and dependency list. The main gist is that we're finally nuking the last pieces of SFML from the project. sfml-audio brought with itself unneeded and big dependencies (libsndfile, libvorbisenc) while at the same time limiting the amount of audio formats mkxp can support (eg. we now get mp3 for free, and wma/midi can be implemented by extending SDL_sound directly). The increased control gained by interfacing with OpenAL directly will also allow for easy integration of a dedicated audio stretcher (librubberband), as well as enable us to implement looped ogg vorbis (via the 'LOOPSTART'/'LOOPLENGTH' tags), as required by RGSS2, in the future. The FileSystem class has had its SFML parts removed. Aditionally, audio file extensions to be supplemented are now automatically detected based on how SDL_sound was built (ie. if no mp3 support was built, mkxp won't try to look for *.mp3 files). The final used extension can be optionally returned by 'openRead' calls so SDL_sound and SDL2_image can immediately choose the right decoder. The OpenAL context is created and destroyed in main.cpp along side the GL context.
