Subject: Rename Bitboards print to pretty
X-Git-Url: https://git.sesse.net/?p=stockfish;a=commitdiff_plain;h=5f2bf91ad18069e77e5c0e32c387b2200abd94d9

Rename Bitboards print to pretty

To align to same named Position function and
avoid using std::cout directly.

Also remove some stale <iostream> include while
there.

No functional change.
