python3 migration

[je-vv]

Wondering if possible to migrate to python3 as the dependencies are available for python3 as well. On a 1st trial, besides the oaut2 lib patch (see issue #166), the following patch for httplib is also required:

But that's not all. Some python3 libraries have changed substantially, therefore, there errors to be solved like:

...
File "/usr/lib/python3.5/tempfile.py", line 483, in func_wrapper
return func(*args, **kwargs)
TypeError: a bytes-like object is required, not 'str'

So, more fixes are required...

It's be awesome if you might start introducing these changes. Furthermore, you'd be a rockstar in my book if you could write some unit-tests for the affected areas.

Naturally, I'd provide any support that I could. I'd even mention you in the documentation for helping with the effort. Hello egoboo.

I believe i have made all the changes necessary to move this project to python 3 (3.6).
I have tested it out by using all the features, but i'm not sure what unit tests would be useful here.

Merged.
