Smallbrain v2.0

Im happy to release Version 2.0.
Since version 1.0 a lot has happened and it is now ~190 elo stronger.

Changes

All changes are primarly search related, although there a few additions to time management.
A few speedups were made in the move generation as well as makemove function.
No changes in the evaluation of a position, it is still only psqt + material count and a small bonus for high rank pawns.
