Dimensiomancer armored vehicle json conversion (please help test)

Ok this should be all the armored car stuff from #2594 converted to json.  Well, I say "should", because when I tried to start Cata to test this, it immediately crashed, didn't even get Cata's debug window.  Not sure what the problem is, I'll rebuild the whole thing and see if it works, problem may be on my end.  Here's what I've got in the meantime, note this is only the json stuff, not the Magen.cpp additions to make it appear randomly in game.  You should still be able to summon it with the wish menu though, so if anyone has time feel free to test this and I'll see if I can fix whatever is causing Cata to CTD on my end.
