Bug report: UNDO feature does not handle layer delete properly.

[lulay14]

The undo feature does not properly handle deleting a layer item.

Problem: UNDO feature sometimes undoes more than a single action. It undoes an object deletion when it should not do so. It also undoes deletion of objects in the wrong order.

SCENARIO 1:
-------------------------------
How to replicate: Create TWO layer items. Delete both in the layers menu. Hit "UNDO".

Expected behavior: Only the most recently deleted square should reappear.

Actual behavior: Both items reappear.

SCENARIO 2:
-------------------------------
How to replicate: Create THREE layer items. Delete item 3, then item 2, then item 1 in the layers menu. Hit "undo".

Expected behavior: Only the most recently deleted item should reappear.

Actual behavior: item 1 and 2 will reappear. Hitting UNDO a second time will cause item 3 to reappear (which should have been the first item to reappear)
