YUI produces invalid XHTML

A default installation of the YUI Editor module produces invalid XHTML, including <A> tags.

A quick search of the YUI issue queue shows a potential solution to this problem.

I have tested adding:

markup: 'xhtml'

(as suggested by the YUI bug report) to yui_editor.js which produces the desired behavior (valid XHTML).

I haven't included a path, since I thought it would be desirable to have this be a configurable setting. My javascript skills are lacking, and I wasn't sure how to add this variable setting.

If desired, I'll happily upload my (simple) patch.
