- got rid of silly #define ..._BIT, #define ... (1<<..._BIT) stuff

- switched almost all uiDefBut(..., TOG|BIT|..) to use UiDefButBit and the
   name of the actual bit define instead of just a magic constant, this makes
   searching the code much nicer. most of the credit here goes to LetterRip
   who did almost all of the conversions, I mostly just checked them over.
