When enabled, custom reactions will begin to produce gloves in sets, based
on the number of hands the job performer's race has, and set the
Handedness flags accordingly.
The "createitem" plugin already contains a simpler workaround (which
doesn't check body plan but instead just produces pairs), but it shouldn't
trigger when this tweak is enabled (unless you use it on a creature which
has been modded to only have "neutral" hands).
