Pcbnew: push and shove router fixes.

* Fix segfault caused by invalidation of the end item by
  PNS_LINE_PLACER::UpdateSizes().
* GAL zone drawing tool updates the ratsnest after zone drawing is complete.
* Fixed performance issue in zones processing using strict simplification
  only for the final filled area.
