Used original 64-bit frameworks: SDL2 v.2.0.5, SDL2_image v.2.0.1,
and from SDL2_mixer v.2.0.1: Ogg v.1.3.1 and Vorbis v.1.3.3.
For potential custom compiling AC for 32-bit Mac there will be needed
self-compiled 32-bit frameworks.
Launcher has to be compiled as 32-bit, otherwise it won't start
nowadays.
