Edit Categories Page
-----------------------------

Add Headings to Edit Categories Page for Each Context Level

• Will add headings to edit categories page and below each heading there will be a list of categories in that context. Edit Categories page will then have the structure as shown here
• The contexts available depend on where you are editing the categories from. Thus in one course you only see that course's context, any parent course categories contexts and the site context. When in the site context you only see the site context.
• Order of listed contexts is most specific to least specific. Questions only for this module, for this course, for Course Categories, for Site.

Add Up / Down Action Buttons
----------------------------------------

These will work as discussed here http://moodle.org/mod/forum/discuss.php?d=67006#p302942 - I like the first option and not the alternative I discuss.
