Add MIF highlighting in Insight (see #10778)

This is a collaborative effort between @bpindelski and @jburel to enable MIF highlighting in Insight. The colour used for the text foreground in the list view can be configured in ``dataBrowser.xml``.

To test, open a multi-file image set (e.g. lei) in Insight and compare if the client does the same as Web with respect to indicating images in the same fileset. Check the thumbnail and list views.
