This uncovered a memory corruption bug in MODULE's move operator,
several bugs in MODULE's move and copy constructors, and a bug in
BOARD's GetItem() call.
It also bumps the file format for saving/restoring groups inside
footprints.
Also simplifies groups so that other areas of code that have to know
about them at least don't have to know as much. One of the simplifications
is to not worry so much about empty groups until save time; others are in
the access logic to parent groups.
Also simplifies user model slightly by removing Merge and Flatten
(which are just ungroup/group and ungroup/ungroup/.../group).
Also allows multiple groups to have the same name. This is useful when
using groups for a classification system.

ADDED memberOf() function for DRC rule expressions.
Also fixes a bug in several of the pickers where the event wasn't
being correctly passed.

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.
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.
SetPosition() only changes the base position of tracks, we need to use
Move() to move the whole element.
This also cleans up white space and group handling in ratsnest

This introduces layer handling to a lot of the geometry routines.
Many of them don't do much with it now, but it does help multi-layer
zones and will help when padstacks are implemented.
