codemirror box redo
* redo the box in app.haml that was supposed to hold code
* it actually works now
* has line numbers (ooh, ahh)
* seems to completely ignore the fact that my code is over *there* and is putting the cursor in an odd position, that's a bug to fix later
* also i'm committing this so i can merge w/the edits i made yesterday
Merge branch 'develop' of https://github.com/cricket-ide/cricket into develop
* see, this is what i wanted to do
