Show custom core properties in core admin section of web gui

Would be great if custom core properties (key and value) would be listed in Core Admin section of the web gui.

If I have a file called "solrcore.properties" in an instance dir with content like this

foo=Hello
bar=World

, link that file in "core.properties" with "properties=solrcore.properties", I think it would be useful if I could see those custom properties somewhere in the web gui.

The same applies of course to the old-style solr.xml approach (custom properties as property elements inside a core element).
