Many slight changes: more elegant escaping. More commenting. Main function now gets input-file from first argument and output from second, stdin & stdout if they aren't provided. Makefile should have less overhead (different commands are now more spread out), but I'm not quite sure it works a 100%. Lexer now counts line-numbers into yypos, though columns aren't accurate.
Removed many output-files. (Added them to .gitignore, don't know when Git will start ignoring them). Correctified LICENSE and updated README.
