This bubbles up the call to got_get_repo_tags from gotweb_render_tags
to its caller, gotweb_process_request and gotweb_render_summary.  It
helps simplifying gotweb_render_summary and making it easier to
templateify, but also helps in untangling a bit the code.

At this point gotweb_render_tags becomes just a wrapper to
gotweb_render_tags_tmpl so switch completely to it.

It may help in revieving the diff remembering that
gotweb_render_summary calls gotweb_render_briefs before rendering the
tags, where qs->action is assigned to BRIEFS.

ok?
