PokerTH orphaned

[Susi Lehtola]

Hi,

I've just orphaned PokerTH, since I'm trying to free myself some time
and I don't use it myself.

PokerTH does not currently build on rawhide, since OpenSSL support has
been dropped from GnuTLS a week ago (BZ #726697). Getting it to build
again would then require building against OpenSSL (and asking upstream
for a GPL license exception), or shipping a private copy of GnuTLS.
