[PythonCAD] More entity modification changes now available at repo

[Art Haas]

Hi.

I've switched the code that changes the style, linetype, color, and
thickness values of GraphicObject instances to behave in both
'select->act' and 'act->select' modes. Things look like they work
right, and I'll be continuing these sort of changes over the next few
days. Just do an 'svn update' and you'll get the changes to play with.
