Disabling internal book

[SzotsGabor]

Hi Michael,

For testing purposes I would like to be able to switch off the internal book. As there is no UCI parameter to do that what change should I make in the sources to accomplish that?

EDIT: I think I've found the solution: in uci.c I changed search.use_book = 1; to search.use_book = 0;
