I was thinking we'd leave `contenteditable` as a type and add an `aloha` type as well.  It's not much additional code and we may have use for contenteditable at some point, plus I think the code for handling aloha events will probably be different.  There's already a place for it on line 70: `when 'aloha' then console.log 'FIX: enable aloha'`
