To avoid nasty bugs due to silently overriding of
common operator we enable the templates on a type
by type base using partial template specialization.
No functional change, zero overhead at runtime.

This is tricky because there are some special
binary fnctions with SquareDelta that we should
leave as they are.
Also note that we needed to add Unary minus template
to fix a comile error in SERIALIZE_MOVES_D macro that was
triggered because now we don't allow conversion to int.
No fuctional change.

Doing the conversion the compiler is now able to
spot two possible ambiguity calls that now we can
easily fix.

Square and piece colors are two different things,
so use different types to avoid misunderstandings.

Less invasive then previous patches, but still a good
enhancement.
Also some indulge on STL algorithms :-)

It is more clear, at last for me.
Also cleanup evaluate_rook() and evaluate_queen()
