Slight change to soundux.cpp.
Decide whether SuperFX and SA-1 chips are enabled only once per frame. This saves a few million instructions per second. (Inspired by Snes9x-Euphoria)
Reverse the loop in MixStereo such that instead of "for each channel, for each playback sample, add into the mix buffer", the playback sample is instead written to the mix buffer only when fully mixed from the 8 SNES sound channels.

Verified working with Secret of Mana, Super Bomberman 5 and Super Mario World.
Fix Tools/Global hotkeys/* refusing to work by touch.
Fix uninitialised memory access in pitch modulation.
Release 1.24.
