Adding defines for NeXT special keys and fixing the 'delete' remapping.
Creating true typedef for key lookup table and switching to standard KS_* values.

Fixing NetBSD's mapping for backspace key.
Switching to do mapping of special keys based on the KS_ constants.
Making Control and Command key mappings match with the physical keyboards.
Fixing, you know, uppercase keys as well as making it so all numpad keys work.

another way to do it right now.
Merge pull request #2 from mgrdcm/cleanup
