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
