Make the DYNLOAD LoadFSynth function non-inline
Disable the autowah effect

There's apparently some issues with it causing noise or killing the output. It
might be due to the per-sample changes being too harsh for the filter to keep
up with, but it's not something I can take care of in time for release.

This commit should be reverted after release when work on fixing it can resume.
Add a 48khz HRTF data set

Made by simply using makehrtf's resampling option with the 44.1hz KEMAR data
set.
Modify CPU extensions and effect options to be enabled when checked

It looks nicer and more featured for options to be checked when they're
allowed, rather than when disallowed.
