Enable three-way turnouts with proper conns support on all sides
I chose to make three-way turnouts have 5 conns (last one is not used) so
that they can be distinguished from crossings easily without refactoring the
code. Three-ways should have their last entry with {["3"]=0} instead as a sort
of internal mark.
