Rodent 1.1 released

[PK]

Right now I'm running some tests for fun, inspired by the post by Ed Schroder (http://talkchess.com/forum/viewtopic.php?t=49421). Tu cut the long story short, I made two alternative king safety functions: approximating scores returned by Stockfish and those described in Toga Log User Manual. I don't go as far as changing data structures, everything is driven by tables and uses just one additional switch instruction, so speed loss is negligible.

The great thing is that scores are really close, so far within error bars, and next Rodent will definately use this stylistic feature. Default setting is not very attack-minded, Stockfish-like often plays with a material deficit, Toga-like (the furthest removed from the original) can be regarded as something of a middle ground.

This will fix unfortunate problem that under current settings Attacker personality does not want to attack.
