Proposed release 1.6.1

There are just under 2 months since 1.6.0 was released and I suggest rolling out 1.6.1. A few semi large changes are already in there, most notably django 1.6 support and the rework of the pynag forms.

This is a good time since there are a few larger pull requests pending which deserve it's own release.

Please chime in if there are any issues, I plan on releasing this week if there are no showstoppers.
