Using Kodi's JSON RPC, Kodi may return less items than requested, even
if there are more items available. The old method of determining if
more items are available by checking if the amount of items returned
equals the amount requested does not work in these cases. Therefore,
we now use the returned List.LimitsReturned to determine if there are
more items available. If List.LimitsReturned.end equals
List.LimitesReturned.total we assume we retrieved all items.
