Always look for pre-existing undo/redo record. Checking for IsNew()
is less robust and should be avoided. Also moves the checking to a
location where it will be easier to ensure that it's uniform.
Push get-undo-level-item processing down a level so it is uniformly
called.
Make sure tables & labels are uniformly handled.
Remove incorrect usage of Get/SetGroupId() for storing lastPin
(which we don't use anyway).
Lists of deleted and changed items MUST include the screen pointer.
An item could be changed on one screen but not on another.
Also tightens handling of PCB_NETINFO_T items, which are not in the
view.
Also fixes a bug where there is no increment parameter if you assign
the base increment command to a hotkey.
(This was discovered while testing the above changes.)
Also fixes a bug where delete during a move in PCB Editor did an
undo instead of a delete.
(Again, found while testing above.)
An experiment was also run to collapse shared parts of SCH_EDIT_FRAME
and SYMBOL_EDITOR_FRAME into SCH_BASE_EDIT_FRAME. However, sharing the
undo code actually increased complexity, and there was very little else
of value in SCH_BASE_EDIT_FRAME (other than the Increment() routines).
This also removes the GROUP/UNGROUP-specific undo actions.
This also fixes a bunch of undo bugs when duplicating
group members, creating pins, etc.
This also fixes some undo bugs when dividing wires etc.
This also fixes some bugs with new sch items not
being created within an entered group.
Recommendation is to avoid using the year nomenclature as this
information is already encoded in the git repo. Avoids needing to
repeatly update.

Prior to this change, the schematic connectivity was updated any time a
change was made to a connectable object. Now the connectivity is only
updated when an object change actually affects the connectivity. Other
properties like line width, fill type, custom fonts, etc. will not cause
the connectivity graph to be rebuilt.
The SCH_COMMIT flag SKIP_CONNECTIVITY has been removed. All schematic
objects can test if they are connectable and if there have been changes
to any connection properties that require a connectivity rebuild.
Remove duplicate rebuild connectivity calls from editor control tool.
This was causing the tangling end test to get called four times on every
undo and redo action because the dangling end test is already called in
the connectivity graph calculation code.
Update connectivity when changing label names which fixes an unreported
connectivity bug.
