Add Rich Text Editor 

Replaces NB's <code>textarea</code> with a Rich Text Editor, using the CKEDITOR library. Functionality includes Math Formula Formatting and Code Syntax Highlighting. 
it displays everything on a line with an ellipsis because of the following CSS formatting: 
 div.location-shortbody-text {
￼white-space: nowrap;
￼overflow-x: hidden;
￼text-overflow: ellipsis;
￼font-size: medium;
￼font-family: arial;
}
I don't actually know if having a snippet optimized things or not: It does makes the leaf of the DOM node smaller, but since the browser doesn't render more than what it needs to, I don't know if this makes any practical difference. That's a question for a CSS / browser expert :)
