No longer needed.
No need to use LWPCookieJar() since we're not reading or writing the
cookies.
TiVos have started sending out already-expired session cookies. But it
turns out that the TiVo just wants an "sid" back; it doesn't matter what
it says. So, construct a bogus cookie with this value. (To put it
another way, this is a workaround for the "400" errors that prevented
ToGo from working.)
