Bread Engine has been updated to version 1.0.0!

The patch version numbers were starting to get large... From now on, I will try to follow semantic versioning.

Bread engine 1.0.0 features null move pruning which makes it around 25 elo stronger than version 0.0.10 in short time controls, and around 55 elo stronger in long time controls.
