Patch with fallback scancode mapping

I use a custom X11 keyboard layout which maps non-ASCII characters to the top
row of alphanumeric keys. This causes the X11DRV_InitKeyboard() heuristics to
fail and the number keys get high scancodes (0x60+) which are generally
unsupported by Windows software. This causes issues mainly in games.

For example in Gothic 1, the number keys are used to switch between melee
weapon, bow and magic. In one of the main quests, you need to cast a spell. But
on my machine the keys for selecting spells have wrong scancodes in WINE and
Gothic doesn't allow them to be remapped. This means that the game cannot be
completed.

Here's a patch that'll fix the wrong scancodes by mapping X11 keysyms to US
QWERTY layout.
