Key bindings layer: skills on 1-7, weapon sets on F1-F7

Raw WM_KEYDOWN/WM_KEYUP are handled in both window procedures (the game
swaps 0x8110d0 and 0x8122a0 with SetWindowLong; 0x8110d0 is the in-game
one). Bound keys are swallowed and post the original hotkey's key event
to the kernel, so F-keys work and bindings are layout independent
([keys] in sacred_re.ini). Replaces the WASD hotkey remap and the digit
swap; W/A/S/D and the digit row no longer reach the game. Skill keys
still cast through the right mouse button. Enabled switches removed.
