Function OrderedAA.dirtyAppendKeyValue

This function should not be used by sane people.

void dirtyAppendKeyValue (
  KEY key,
  VALUE value
);

Workaround for storing multiple values for a same key like in half-broken nwn2 gff files. Only the newest value will be accessible using its key. The older value will only be accessible using byKeyValue or iterating with foreach.
