Input system no longer respects key swaps via Windows Registry

[Tom Schultz]

I have been using SharpKeys to turn caps lock into left control for years (ergonomics). 99% of games have no problem with this, and neither did Qud until this patch. Now that key is being read literally as caps lock and can’t be used as a modifier with directional keys.

Ideas:

• Checkbox to use the keyboard layout to identify the key (displayName?) instead of the scan code
• Allow the use of caps lock as a modifier
