add default remote URL with contrib json files

See Benjol#6

This is the simplest possible step towards implementing per site
remotes. The only thing happening here is the current remotes field is
pre-populated with a pre-defined location baset on the current site that
has jsonp files setup. Only works for sites that have contrib entries
already setup.
