[Suggestion] Add buttons to simplify enhancements settings

[Max833]

I think most people don't know that bsnes has a fast mode and an accurate mode and they are really confused when they see the enhancements settings. My suggestion is to add something that simplify this. byuu already did this with the driver settings:

Maybe we can do the same for the enhancements window. Something like "Accurate mode", that disable all enhancements and "Fast mode" plus a short description.

This seems like a good idea! I would accept a patch for this.
