fixed: in Big::FromDouble(double value) (32 bit version) 

buffer overflow in referencing to UInt<2>
       (instead of m.table[2] should be m.table[0])
       this was used when: E=0 and F is nonzero (double "unnormalized" values)
       it produced incorrect mantissa (on about 8th decimal digit up)
