The dashboard will show up to $dashboardLimit future
entries; if the number of future entries is still
less than $dashboardDraftLimit, it will add drafts
up to $dashboardDraftLimit.
If there are _no_ future entries, $entries is no
array, but has a value of "1"; count($entries)
will then be one, too, so one draft less will
be shown.
Closes#465.
