Add "Generated by CoffeeScript #{version}" insertion in processed cs files

[Meettya]

Need to check and fix strange behavior. At dendrite

// /Users/meettya/git_hub/dendrite/lib/dendrite.js 
// Generated by CoffeeScript 1.7.1

and

// /Users/meettya/git_hub/dendrite/web_modules/lodash.coffee 

(without CS version)

Oh! Nevermind, first - from previously compiled step, second - because clinch dont insert this line. In other word - task must be renamed to "Add Generated by CS comment"
