Python 3 not supported, lack of support undocumented in setup.py

[andrewsg]

Django now fully supports Python 3, but this plugin does not, and setup.py does not specify supported versions. As a result, this plugin will install but crash if Python 3 is used.

According to the 2to3 tool, Converting the plugin to support Python 3 will involve at least the following:

• changing all relative imports from e.g. import models to from . import models
• migrating from urllib and urllib2 to the new urllib modules and submodules
• changing try/except deprecated syntax from e.g. except ValueError, e: to except ValueError as e:

... and some other small changes.

It should be possible to support python 2 and python 3 simultaneously.

I might be able to contribute to this task once I have more experience with the module.

Supporting both Python 2 and 3 has been added in 0.2.0.
