lmark.synchronized_markers(): apply one marker's effects to multiple points simultaneously.

synchronized_markers() takes a marker, and a list of method names to override,
and returns a set of markers that fire simultaneously, to allow, say, fog
machines that fire at random intervals, but always fire in unison. lm_mslav.lua
has details. volcano.des has an example volcano entry vault that uses this.

Allow fetching a list of Lua markers/marker positions by property value.

Renamed dgn.find_marker_prop -> dgn.find_marker_position_by_prop.

s/helper/listener/ for fog machine listeners.
