[GNC-dev] Fixes for python 3

[c.holtermann at gmx.de]

Hello all,

I'm looking through the python bindings for python 3 issues.
I've created a pull request for some smaller fixes.
https://github.com/Gnucash/gnucash/pull/415

I'd like to have some sort of To Do List, collection and discussion
about checking the existing python parts for compatibility
with python 3.
I don't think it's quite fitting to file a bug report for it's more
of a project but I don't see an organizational approach
that is more fitting.

regards,

Christoph
