[vtk-developers] Update: Making Tests Python 3/2 compatible.

I've looked at TestTemplates.py, and it is going to require that I give it
some special attention in order for it to provide the same coverage under
Python 3 as it provides with Python 2.
For proper coverage, that test needs a string that cannot be expressed in
ASCII, so I'll just build such a string at the top of the program:
# create a unicode string for python 2 and python 3
if sys.hexversion >= 0x03000000:
francois = 'Fran\xe7ois'
francois = unicode('Fran\xe7ois', 'latin1')
On Python 3.2, only TestTemplates and the Tk tests failed. I'll fix the
former and take a look at the latter.
Also, if you don't mind, I'd like to cherry-pick your commit onto my
python-py3k branch and submit as a new merge request. That will allow us
to keep all the Python 3 commits as a contiguous set.
