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.
