A couple of WYMeditor updates
Turning the editor back on for the Content Manager pages
Fixing the Change About page
Fixing two corner cases with search: no posts, and nothing found, closing Issue 4038 <https://redmine.iopen.net/issues/4038>. Also, using the new animated swirl icon
Adding the URL for the old (compatible) JavaScript back
Adding an interface *back* so I can fix GS Team (I hope) and a white-space 'n' egg cleanup
