Enforce existing 5 action hardcoded undo limit.

This was present in the code but not enforced, which led to a memory leak over time as part properties were changed, whether by viewer, script or another source.
This commit enforces that limit, which will soon become configurable.
Regression test for undo limit added
Should help with http://opensimulator.org/mantis/view.php?id=6279
