Requires accompanying gameDir change.
MercOpinions.xml now only contains opinions that are not 0. A new tag with fields "id" and "modifier" are used instead of old ones that had 255 <Opinion%d> $value$ </Opinion%d> tags for all profiles.
Loading time of MercOpinions.xml went down from ~4.047 s to 0.011 s due to this change with default 1.13 VFS config.
A small cmd utility tool for converting existing MercOpinions.xml data into the new format is available at https://github.com/Asdow/JA2-ConvertXMLData/tree/master
