Return to lonmenu.pm CVS log

Up to [LON-CAPA] / loncom / interface

Fix bug 262.  lonxml.pm now checks to see if you have permissions to edit
the currently view resource.  mydesk.tab no longer calls cstrgo in menu.html
so cstrgo and is_editable_resource (javascript functions) have been
removed from menu.html.  lonmenu.pm was cleaned up.
This has been tested for authors and co-authors and across domains.
