Ruby Rake::todo

·
Simply reads the set directories, and scans the .rb files for @todo, will report the line before and line after @todo 
Needs console coloring to work: http://snippets.dzone.com/posts/show/7148

EDIT: After readind Michals comment i decided to change it, i hope it all works a bit faster now and doesnt have to give in on functionalities.
