- undelete after recursive delete now brings back everything deleted in that

operation, not just one object at a time
- vector reference counting is not needed now that we have recursive delete.
  Removed it.
- completed recursive delete of vectors
- gridify: give new vectors a minimum length, so that we don't get a weird
  display when starting a new footprint.
