Needs update form Ruby 1.9.2

Looks like there's a few different errors preventing this awesome bundle from working on Ruby 1.9.2.

I am getting a no method error in run_script.rb (str.map vs. str.chars.map) and also several warnings with the regex patterns on lines 46 and 49. I think there's a few other issues as well but not certain.

Does the encoding have to be declared in those files?
