update rof_object_properties

Now has aerostats, bridges, trains, ships, factories, railway cars,
pillboxes, churches, some airfields, etc with the mission editor 'model'
and path... most things that were already in there.  There are a few I
haven't found yet, like empty flatcars and there are a lot of 'blocks'
that aren't in there since I haven't seen them in mission logs.
