FC2Live sends cookies with value "deleted" to invalidate previously set values. In the same request
they send new values, too. That confused OkHttp. We now use a custom cookie jar for FC2Live, which
ignores cookies with the value "deleted"
This is done, because there might be some special conditions for the
player to work. For example on fc2live a websocket has to be open while
the player is running. The SiteUI can handle these cases transparently.
