+changes 2015-06-24:
+- xxx.get(...) changed to xxx[...]
+- xxx.set(...,...) changed to xxx[...]=...
+- function placeRandomlyNotColliding(cr) explicitly called when adding a new creature, and removed collision checking from onCreaturesBorn() which is also called when "growing" (since "growing" is implemented as creating a new creature in place of the old one, so onCreaturesBorn() is also called)
+- use creature's center (not the bbox corner) when growing
+- added "S" receptor to visualize the difference between diplo and haplo generations
+- signal.value is a MechPart (a reference) so it does not have to be updated after changing the object location
