#148: Standalone solver option nodeStrategy broken for up/down selection

 Some of the values for this option are updepth, downdepth, upfewest,
 downfewest.

 The code to distinguish the up/down direction seems to depend on the
 parity of the integer representing the option value, but this is the code:

 int way = (((nodeStrategy - 1) % 1) == 1) ? -1 : +1;
 babModel_->setPreferredWay(way);

 It seems that this should instead be:

 int way = (((nodeStrategy - 1) % 2) == 1) ? -1 : +1;
 babModel_->setPreferredWay(way);
