I actually fixed this problem about three weeks ago, but neglected to
publish the code.  :(  In the latest version, all of the objects which the
SkinScript compiler creates are derived from a class "NullProvider" which
has empty methods for all the _objectXing events, including _objectChanging.

Luckily, there is not much more to do for the new release (0.4.2b1) besides
updating the release-related files, and perhaps a bit more work on
improving the management screens for SkinScript methods.
