Testing is not clear. Probably we need to test
at deeper depths to have some clear results.

Implement Last Seconds Noise (LSN) filtering
...
When an engine is in deep trouble at few
seconds from time limit then giveup without
fighting anymore.
This is used to reduce "lucky draws" and time pressure
blunders noises that can obfuscate results during tests
blitz games (typical one minute games).
Goal of this technique is to reduce number of matches
needed to reliably prove then an engine A is stronger
then an opponent B.

Fix a couple of bugs (fallout from previous patches)
...
After testing and comparing output with standard Glaurung
a couple of issues arised.
A default value was wrong and init_uci_options() missed a couple
of stringify() calls. Also storing bool values as "false" and "true"
needs some care.
