gfx_sdl: fix two bugs that both broke capslock and numlock and caused pad numpad remapping

Part of bug #45

The bugs are entirely independent:

1) SDL 1.2 on Window has a bug where if capslock or numlock are on when the
   program starts they appear off, and will always be reversed. Work around by
   getting real state with the winapi
2) We initialised the keybdstate array to zero, so capslock and numlock appeared
   off until they were pressed for the first time on non-Windows OSes.

Bad numlock state leads to bad numpad remapping.
