mod_muc_markers: replace configurable multi-marker tracking with better system
Now tracks a single marker, but automatically applies rules from the XEP about
"higher" markers implying "lower" markers - i.e. "displayed" implies "received".
Still, just a single marker is tracked and synthesized at all times (the one
configured with muc_marker_name).
