Pondering version

[Simon Waters]

The problem with pondering not playing a second game on FICS was
the same as the bug in the pre-release version of 5.05 which
segfaulted.

Does this mean segfault has become silent thread death? Ouch.

Anyway it was a stupid bug I introduced - I must of had a bad
day that day. Anyway applied the memset change in players.c, and
all is well at the moment.

Going to let it rake up some games on FICS as nextgnu see if the
rating has changed.

Noticed some bad pawn play as black, with doubled pawns all over
- I smell a bug in ScoreP.
