fixed: Big::BigAnd() Big::BigOr() Big::BigXor() should have set NaN

when the argument was negative (they only returned 2)
added: some missing operators 
       UInt::operator~()    /* bitwise neg  */
       UInt::operator&()    /* bitwise and  */
       UInt::operator&=()
       UInt::operator|()    /* bitwise or   */
       UInt::operator|=()
       UInt::operator^()    /* bitwise xor  */
       UInt::operator^=()
       Big::operator&()
       Big::operator&=()
       Big::operator|()
       Big::operator|=()
       Big::operator^()
       Big::operator^=()
       for Big<> we do not define bitwise neg
