A lot of things happened here:
* everything menu-related was moved out of lonxml, and into lonmenu
* thus, function calls to registerurl, loadevents and unloadevents modified
* fixed lontex.pm, which actually did not call the right routines
* put in calls to lonmenu::menubuttons, which is supposed to insert buttons
after the body tag in "textual mode" - this function and registerurl will
be unified (buttons either in Remote or on top of page)
