**This commit changes functionality**, please read

Remove legacy code that enabled / disabled mesecon wires that were placed 2 blocks below a
pressure plate. From now on, please place a vertical wire at that place. That way, no false
signals will be triggered (the wire won't "flash" turned off if you enable it by a pressure
plate and turn off a switch connected to it).
If you depend on this functionality, please just revert this commit. That should be possible in
the near future as well, since no major rewrites are planned for mesecons_pressureplates. In the
long run, please update your mesecon strucutres to use vertical wires instead of relying on this
old hack.
