Draft: DraftGeomUtils clean up imports, and Python 2 compatibility

Browse Source 
Small spacing fixes like imports in separate lines
for more clarity, and the position of the license.

Also fix copying of a list in order to keep compatibility
with Python 2.

"""Define geometry functions for manipulating shapes in the Draft Workbench.
These functions are used by different object creation functions
of the Draft Workbench, both in `Draft.py` and `DraftTools.py`.
They operate on the internal shapes (`Part::TopoShape`) of different objects
and on their subelements, that is, vertices, edges, and faces.
