lexer for log files

[brynne8]

I created a lexer for log files. It's because my colleagues often copy log files and send back for us to view. We need some highlight to find out errors. link

PS: I added MIT license to my repo so that you can use my code without copyright issues.

The lexer works better when lexer.FUNCTION and lexer.KEYWORD use different colors.
