this also needed mupen deps updated, and SDL2 compat needed to be fixed. SDL doesnt need to be used anymore, so that's nice
also deleted mupen projects which we don't use anymore
* Wire up host haptics, but only for OpenTK which doesn't support it
and I'm hijacking the Fast Forward hotkey too
* Fix Mupen 64 Vibration DLL
* Enable Mupen 64 Vibration for DirectInput
* Remove unused SDL dep from Mupen input-bkm plugin
this allows it to be built without checking out the deps submodule, I guess
* Fix <OutDir/> in Mupen lib projects
* Remove "Debug" haptic channel and debug hotkey, prepare Mupen
* Fix remaining merge conflicts
* ...with the correct channel name
and hopefully no dangling whitespace changes
* Fix typo from resolving merge conflict, and off-by-one error
