Same problem as 658eed4... Except instead of just making the
comments use #, I'm actually removing some of the codes entirely
because they are of questionable value.
Should fix https://bugs.dolphin-emu.org/issues/12737.
Main Stick is changed to Control Stick and C-Stick is changed to C Stick.
A new ui_name variable is added to ControlGroup so that the UI strings
in DolphinWX can be updated without breaking backwards compatibility
with config INIs and other things that use names as IDs.
Having settings for each game in more than one file is redundant.
Now, region-free INIs are now only for settings, and region-specific
INIs are only for AR codes and patches. Exceptions are made for
titles that share the first three characters of their IDs with
unrelated titles (mostly unlicensed titles and Triforce titles).
He claims they don't work on that revision either, but from a quick
Google they (most of them?) seem to be intended for it, so keep them in
case they're useful for anyone.
