Had a mess with the Line Format function.
Got the Keyword highlight working so that if you had more than one occurrence of a keyword on a line, it highlights them all.
Got numbers working.
Changed the precedence of Strings and Comments. It was highlighting wrong if you had ";" in your code.
Tried speeding stuff up reading the keywords into an array but that seemed to slow it down (thought an array might have been faster than a type).
