+In order to support real rail crossing nodes and finally make the trackplacer respect switches, I changed the connection system.

+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
