If advtrains_train_track is disabled, don't register any tracks that use
its model like the LuaATC automation rail, point speed restriction rail,
station/stop rail.
For LuaATC, the definition for firing an event when a
train runs over the rail needs to be moved into the common defs so that
other mods like linetrack can use that as an interface.
After successfully registering newly-placed ATC rails in the nodedb, the rail's after_place_node() callback
(local apn_func()) immediately cleared it again by passing a "node" object that was actually a player object
and thus had no "name" or "param2" to ndb.update(), which it handled how it should not in this situation.
Since those ndb.update calls were unnecessary anyways, I removed them completely.
duplicate "message" to "msg"
make operation panel "cracky"
remove inexistent dtime_s parameter
add bones:bones to the list of not_blocking_trains nodes
