This makes it clearer that the overrides are not inverses of each
other -- one overrides the flashing state and the other overrides
the connection state (to other zones, not to everything).
Also fixes a bug where we were failing to check the force-no-connect
for pads.
If the pad hasn't already been owned by another zone, and the zone we're
currently filling can connect to it, then we want to try to flash it even
if it's not connected to anything else.

Also adds some debugging to try to catch dangling pointers.
Also adds a cache for group bounding boxes (which will be expensive
to calculate for large groups).

1) The highest priority zone that a via/pad collides with "owns" its
connectivity state. Once set, lower priority zones cannot change it --
and in fact, if they would have connected to it are forced not to.
2) The connectivity state goes with the zone fill state, and therefore
must be saved in the file.
3) Display of remove-unconnected's pads is no longer done in GetViewLOD()
(which isn't called for selected items), and is instead done in PCB_PAINTER.
This allows us to draw the full pad in outline mode when a via/pad is
selected which would otherwise only show the hole.
4) Note that in some cases this will still generate DRC errors -- in
particular when a via nearly collides with a higher priority zone it
won't get "owned" by that zone and may therefore have insufficient
clearance if said zone concludes it's unconnected and a subsequent
(lower priority) zone connects to it (causing it to now become flashed).

When wxAny holds an enum, it cannot be compared with an integer due to a
missing conversion function. In such case, conditional properties
compare a raw value rather than wxAny.
When building the connectivity database, we should not be using the
connectivity to check for shapes.
To make this deterministic, we introduce two flags (ALWAYS_FLASH and
NEVER_FLASH) that are used with connectivity building to determine
whether a pad is flashed for connectivity or not. ZONE <-> PAD/VIA
connectivity will be checked with ALWAYS_FLASHED and all other
connectivity will be checked with NEVER_FLASHED if they are marked for
potential annular ring removal. If they are not marked for removal,
they will be checked ALWAYS_FLASHED.

ADDED zone_connection constraint.
ADDED thermal_relief_gap and thermal_spoke_width constraints.
ADDED angle override for thermal relief spokes in Pad Properties.

The pad comparison function was never updated when chamfered rectangular
and custom pads were added so if more that one variant of either of those
pad types existed in a design, only the first one would get generated and
assign to every pad of that type.
The custom pad primitive comparison has not be implemented so the exported
designs may be broken for custom pads.
