Add initial version of hilex
hilex is meant to replace hi, based on lex rather than a mess of overlapping regexps. I want to preserve hi's tagging abilities, but that will require some amount of parsing/post-processing, which I'm not sure how to approach yet. Macro lexing for C still needs work, as I want to match strings and comments inside macros.
