More accurate antenna management in Anabatic.
* New: In Anabatic::DiodeWire, use "antennaDiodeMaxWL" to compute the number of diodes to insert in a wire only cluster. Use boxes instead of segments to define the area as segments can be splitted by the diodes inserteds at the DiodeRps stage. * New: In DiodeWire::createDiodes(), specific diode insertion method. Try to instert first in long horizontal wires.
