Avoid constructing an empty tuple in qsearch

Browse Source 
Avoid constructing, passing as a parameter and binding a useless empty tuple of pointers in the qsearch move picker constructor.

Also reformat the scoring function in movepicker.cpp and do some cleaning in evaluate.cpp while there.

No functional change.
