Doesn't support python 3

[filippzaripov]

I'm getting invalid syntax error when starting ckan. "except ValueError, e:" - this syntax is not correct in python 3, but there is no information in docs that plugin working only with python 2.

Possible solutions: Solution 1: fix syntax to "except ValueError as e:" Solution 2: mention in documentation that it's not working with python 3.

I'm running into the same issue. I found this discussion on the migration to Python 3:

https://github.com/ckan/ckan/wiki/Python-3-migration-guide-for-extensions

See issue #238 also.

Also just found #249

Python 3 support was added as part of #249. You can use the v1.0.0 tag onward to get Python 3 support.
