Up to [LON-CAPA] / loncom / interface

Still got a long way to go on the textual interface, but should not
interfere with Remote.
Next steps: write JavaScripts or equivalent to handle function calls
on textual interface, move configuration out of lonmenu.pm into
mydesk.tab (which is part of generally cleaning this up).
