In turns out that the problem is (fortunately) in the shift2 parameter
which is computed in InteractionDispatchers and passed to Ig2 functors,
not in the collider (fortunately). See the attached screenshots -- real
interactions are in green, which potential in violet; the network is as
it should be. When periodicity is disabled with O.periodic=false, one
can see that interactions between neighbouring particles are created (by
the Ig2 functor) just fine, while the other ones are not (they are still
detected by the collider).

Bug description:
This bug was reported first by Jan at http://www.mail-archive.com/yade-users@xxxxxxxxxxxxxxxxxxx/msg02096.html. Interaction accross the periodic cell boundary are being missed apparently, as the attached script demonstrates.
