Implemented Missing String Functions
Four of the new missing string functions for byte stuff.
Whoops had the wrong data type.
Implemented keyboard_check_direct
Implemented numlock functions.
Added the two functions to simulate a key press and or release.
Added 4 extra functions for caps lock and scroll lock.
Added myself to the copyright header.
Readding the old display_reset I had commented out it works fine in
conjunction with the new one.
Added keyboard map.
Implemented the long forgotten keyboard_lastkey
Finished keyboard maps, tested thoroughly with Game Maker 8.1, appears to
be working perfectly the same.
