version 1.3

The purpose of dumb is to be a very simple chess program with only the major search algorithm in it.
Changes to version 1.2:
Evaluation has been rewritten in a more clever and simpler way.
Search has been made simpler, by removing transposition table usage in quiescence and at the root node.
Several code simplification everywhere.
The result is a significantly faster program, and a slighlty stronger program.
