Adds django 1.6.5+ support 

I guess this is the working branch. This PR basically does the following:

* Adds the new Django manage script.
* Fixes syntax issues with forms, the url parameter has changed since.
* Updates the location of certain libraries that were moved since (like the csrf middleware)
* Fixes the type builtin bug with repy_v2 and Django.
* Fixes some old references to plain repy (not v2) code.

It contains the older PR for the setup script. I can remove that if needed.
