[PythonCAD] [PATCH] Fix for undo/redo operations on DimString entities

[Art Haas]

Hi.

The small diff below fixes a problem I found when trying to undo
a color change on a DimString entity. I'm sending this out to
the list if people want to patch their copy of the latest release,
and those of you using Subversion can just run 'svn update' to
get this change as well. Sorry it didn't make it into the last
release.
