These objects can now be used in advanced DRC rules and
not just for keeping things out. Also remove the restriction
that at least one of the "basic" keepout rules must be set,
so that these areas can be used for more advanced rules.
1) better load-balancing for deferred zones
2) sort zones by priority before filling
3) retire BOARD::GetZoneList() which had a horrible performance profile
4) implement a zone bounding box cache
5) better checks for IsCancelled() so long fills can be exited

ViewGetLOD() returns the minimal value of a zoom to show an item.
However a zoom is a double, and using int as minimal value does not
allows setting a correct value in some cases.
If the zone fill failed, then don't add the zone to the
exported VRML because it might not be correct.
Also test that the Python command in DIALOG_SCRIPTING worked.
This dialog actually isn't used anywhere currently, so it
could in theory be removed - but it is simple enough and
it provides a decent testing dialog that it is more work to remove
it.
These settings objects could be created in a constructor/destructor
so we should catch the exception since those are noexcept.
Also change the settings trace to match the other kicad traces
as KICAD_SETTINGS
The first attempt to address this which added back in the zones
with a 0 netcode didn't pick up those with a netcode which weren't
isolated (ie: because there were unplaced footprints outside the
board edges).
The new system gives up on trying to adjust the insulated island
list and just makes a second pass.

Also improves the SNR and consistency of the menu item text. For
instance, a position is rarely useful, while relative sizes can be.
Also removes some unnecessary repitition, such as "Graphic Rectangle"
when "Rectangle" communicates the necessary information.
DIMENSION is now an abstract class and we should cast to
concrete implementations instead.
Also change broken 'return none' to throwing an exception
which will give feedback about what is not supported by
the API instead of silently returning a non-object.
Also fixes a bunch of naming issues, primarily with lowercase for
protected variables, but also some for consistency with other parts
of the code.
Also changes the zone fill radio buttons in Board Setup to be more
generic referring to legacy vs. current, and to have tooltips.
