FireFly v1.1.1
==============
Bug fixes:
----------
	Out of time check disabled after a fail low.  Forgotten to comment out test codes.

	King safety evaluation for uncastled black king.

	Optional indexing file not created for very large (>32MB) book.

New stuff:
----------
	EGTB probeable positions at root are not searched but results read off the EGTB files - saves a lot of (unnecessary) search time.

	Implemented automatic book update.  Now incremental book updates is possible.
