UCI engine opening book

Adding opening book for UCI engines

youtube video example: https://youtu.be/mJ5CDL3GBOo

you will have to add opening book configuration to the ini file of each UCI engine (you can find those engine ini files in "My Documents\CraftyChess\Polyglot" for the installation version of Crafty GUI), here is what you have to add at the start of file:
Book = true
BookFile=C:\Users\Valters\Documents\CraftyChess\polyglot\gm2001.bin

where C:\Users\Valters\Documents\CraftyChess\polyglot\gm2001.bin is full path and filename of the opening book
