Bug 679: Need to be able to disable chatroom.
   Added plc (permission for live chat).
   lonchat.pm and lonchatfetch.pm now both call &lonnet::allowed('plc',...)
   lonparmset.pm, loncreatecourse.pm, and course.initialization.helper
       now all allow setting $ENV{'course.'.$courseid.'.plc.roles.deny'}
       lonparmset.pm also allows the user to set
       $ENV{'course.'.$courseid.'.plc.users.deny'}
   lonmenu.pm was modified to allow us to require the user both be in
       a course AND have permissions.
   mydesk.tab, roles.tab, and rolesplain.tab were modified to include the
       new role.
