Fixed: bug with mist.getLeadingPos where the position appeared to be reversed from what it was expecting
Added: mist.marker.drawZone. This function is a quick and easy way to render trigger zones on the F10 map.
Modified: mist.marker.add to also accept coa as variable name for markForCoa
Modified: mist.marker.add to accept number value for markForCoa
WIP: Updates to message display code. Currently commented out.
