[PythonCAD] New stuff at public repo

[Art Haas]

Hi.

Over the last week there's been new code making its way to the public
repo, but I've not been mailing the list about it. The code is mostly
a new feature in PythonCAD - the ability to rotate objects around
some point - plus a number of bug fixes and enhancements.

To use the rotation, you first need to define the rotation point by
clicking in the drawing or entering the point in the entry box. Next,
you can either enter the angle of rotation in the entry box, or you
click construction lines and the angle between them will define the
rotation angle. At this point, you select the objects to rotate by
clicking on them or selecting them by drawing a selection box.

I've played around with this feature a bit, and it seems to work for
the simple cases I've tried. I'm still fiddling with the code so
it may change slightly in the next day or two, hopefully for the better.
I need to add the ability to use selected objects as the ones to rotate,
for example.

Please do an 'svn update' to get the latest changes.
