[18.12.17] Note on new connection system:
In order to support real rail crossing nodes and finally make the trackplacer respect switches, I changed the connection system.
There can be a variable number of connections available. These are specified as tuples {c=<connection>, y=<rely>}
The table "at_conns" consists of {<conn1>, <conn2>...}
the "at_rail_y" property holds the value that was previously called "railheight"
Depending on the number of connections:
2 conns: regular rail
3 conns: switch:
	- when train passes in at conn1, will move out of conn2
	- when train passes in at conn2 or conn3, will move out of conn1
4 conns: cross (or cross switch, depending on arrangement of conns):
	- conn1 <> conn2
	- conn3 <> conn4
