Rich text box

Added a rich text box component.
Right now using [nicEdit](http://nicedit.com/)
I chose that library because it is light weight and easy to integrate
Still have issues with styling, ie: width is hardcoded and doesn't pickup changes, but still very nice in general

My point exactly, the `id` attribute shouldn't be used for anything else.
