Changelog:
- port: various compilation fixes for OS X [kode54]
- nall: added programpath() function to return path to process binary
[todo: need to have ethos use this function]
- ruby: XAudio2 will select default game sound device instead of first
sound device
- ruby: DirectInput device IDs are no longer ambiguous when VID+PID are
identical
- ruby: OpenGL won't try and terminate if it hasn't been initialized
- gb: D-pad up+down/left+right not masked in SGB mode
- sfc: rewrote ICD2 video rendering to output in real-time, work with
cycle-based Game Boy renderer
- sfc: rewrote Bus::reduce(), reduces game loading time by about 500ms
- ethos: store save states in {game}/higan/* instead of {game}/bsnes/*
- loki: added target-loki/ (blank stub for now)
- Makefile: purge out/* on make clean
