* New feature: Site admin can choose whether or not tinymce is enabled by default. User's may override this setting. Thanks to jjeff for the help with the JavaScripting.
* Smaller sized textareas (signature, site_mission, etc) should default to using the tinymce simple theme. Showed how this could be done at theme level and per textarea.
* Disabled tinymce when editing a PHP node.
