[PATCH] Set environment variables for auth filter.

[Hugo Hörnquist]

Hello again!

A while back I wrote to this list with a problem regarding
environment variables in the authentication filter.
Slightly after I proposed a patch. I'm still interested in
getting this merged.

This patch exposes the CGIT_REPO_* environment variables to
the authentication filters. Which I need for using the
CGIT_REPO_OWNER to give login access. 

I also attached a patch for the documentation, which I
believe should better reflect reality.
