doc webdav: install a dummy DAV handler at / , for Nautilus
The gnome gvfs component falsely requires that / will serve PROPFIND requests. We reuse the static-http capability of the server (force activation rather than opt-in default behavior) and serve pseudo-DAV properties for the root. Conflicts: document_webdav/webdav_server.py bzr revid: p_christ@hol.gr-20101123185011-besih03q4gt2atps
