CGIT_REPO_* environment variables in auth filter?

[Hugo Hörnquist]

I started reading the source myself, and found that
cgit_prepare_repo_env is called after all authentication
filters.

The diff below shows a possible fix. It does however only
apply for authenticate-cookie and body, and not
authenticate-post (apparently due to the repo only being
loaded in the former two cases). 

	diff --git a/cgit.c b/cgit.c
	index 6301b87..7a4978e 100644
	--- a/cgit.c
	+++ b/cgit.c
	@@ -1081,6 +1081,9 @@ int cmd_main(int argc, const char **argv)
			cgit_parse_url(ctx.qry.url);
		}
	 
	+	if (ctx.repo)
	+		cgit_prepare_repo_env(ctx.repo);
	+
		/* Before we go any further, we set ctx.env.authenticated by checking to see
		 * if the supplied cookie is valid. All cookies are valid if there is no
		 * auth_filter. If there is an auth_filter, the filter decides. */
