Update Control Panel with better functionality

[Stardog]

This is a continuation of an issue entered by Jeff.

Additional changes that will need to be made:

1. Order Control Panel tabs like so: Content, Administration, My Page, and by title after that. In MySQL anyway, this query works: select * from controlpanel_tab order by id != 'content', id != 'admin', id != 'my_page', title; because false is less than true in some crazy world somewhere.
2. Order Control Panel Links by label.
3. Remove the link_order and tab_order fields.
