Fix ratsnest calculation for pads connected with zones (GAL) 

This patch fixes a problem with GAL where zones are ignored in ratsnest
calculation.
The problem is that calling RN_DATA::Update on a zone with no polygons
(an unfilled zone) will remove the zone successfully, but then
RN_DATA::Add is a no-op.
From this point on, because ::Update refuses to work on items that have
not been ::Add'ed, the zone is removed entirely from ratsnest
calculation and will only be reconsidered once it is explicitly ::Add'ed
again.
The fix is to explicitly create an empty RN_ZONE_DATA object for every
zone that is ::Add'ed.

A second problem is that the point editor forgot to call
RN_DATA::Recalculate after calling Fill_Zone.
