INI: Extend INI_MS_DETECT to be non-exclusive
This updates the INI_MS_DETECT flag such that it can be
used in combination with INI_MS_MERGE, INI_MS_OVERWRITE,
and INI_MS_PRESERVE. With the previous behavior, to detect
that duplicate sections exist in a config directory, two
separate calls to ini_augment would need to be made:
one with a copy baes_obj and INI_MS_DETECT, and one with
INI_MS_PRESERVE.
