Subject: [PATCH] views: Expose Series mbox

It is possible to download a patch mbox with all dependencies. Now make
it possible to download the entire series. This takes the form of the
following URL when using the default routes:

    /series/{seriesID}/mbox/

Like the equivalent patch and bundle links, this will return a 404 if
'{seriesID}' does not match an existing series' ID. However, a 404 will
also be returned in the series is not complete, as indicated by
Series.total > Series.received_total. You can override this behavior by
providing the 'force' parameter:

    /series/{seriesID}/mbox/?force=1

Note that there are no current plans to provide a series-specific view,
a.k.a.

    /series/{seriesID}/

As a result, this particular URL will continue to return a 404.
