Fix audio volume double/triple-scaling and add About tab

Browse source 
Audio was being scaled by master volume multiple times: once via
ma_engine_set_volume, again per-sound in AudioEngine, and again
via pre-multiplication in the UI. Removed redundant master volume
multiplications so each channel volume is independent and master
applies once through the engine. Added About tab to settings with
developer info and GitHub link.
