To be honest,
My interest in doing this work is to get rid of system.ini from the
Wine tree. While I agree that there's more to do, it's just not up
my alley :) So, this version of the patch still maintains support
for system.ini, just like the old code does, but it also adds support
for registry, which should allow us to move stuff there.
So here it goes again, I hope this time it's acceptable.
ChangeLog
Move MCI settings from system.ini to the registry.
Simplify code, make the configuration values dynamic.
