Retire the misdesigned StepAttacks[] array. 

StepAttacks[] is misdesigned, the color dependance is specific to pawns, and trying to generalise to king and knights, proves neither useful nor convinient in practice. 

So this patch reformats the code with the following changes: 
- Use PieceType instead of Piece in attacks_() functions 
- Use PseudoAttacks for KING and KNIGHT 
- Rename StepAttacks[] into PawnAttacks[] 

Original patch and idea from Alain Savard. 
No functional change. 
Closes #1086

Copy killers in the movepicker 
ss->killers can change while the movepicker is active. 
The reason ss->killers changes is related to the singular 
extension search in the moves loop that calls search<> 
recursively with ss instead of ss+1, 
effectively using the same stack entry for caller and callee. 
By making a copy of the killers, the movepicker does the right thing nevertheless. 

Tested as a bug fix

asmFish: trim off the cruft in official stockfish and make a lean and mean chess engine. It is 99.9% official stockfish as there are some inconsequential functional differences in official that were deemed too silly to put into asmFish.

pedantFish: match bench signature of official stockfish to catch search/eval bugs more easily.PedantFish 2017.04.26 - download

Use int instead of Value for history related stats. 
history related scores are not related to evaluation based scores. 
For example, can easily exceed the range -VALUE_INFINITE,VALUE_INFINITE. 
As such the current type is confusing, and a plain int is a better match.
