Title: coffeescript filter + markdown filter mods

* added a coffeescript filter (w/ tests)
* modified the markdown filter to handle interpreters with a specific invocation syntax
* removed unnecessary Maruku filter
* added Redcarpet 1.x / 2.x detection
* added Gemfile to handle development dependencies

I did basic testing on the Markdown stuff, but since there is no test structure for external filters it should probably be field tested. plus im doing this at 2:30am...
