SVN commit 546593 by staikos:

Add a dialog that shows metadata for datasources from the data manager.  It's
low impact here.  I haven't really tested displaying any data since I don't have
any datasource that has metadata right now.  If any source plugin wants to put
it into variables, it can do it itself.  Nothing ever precluded this.  I'm not
going to put anything inline in the data manager because it's just too much data
and the horizontal scroll bar will be quite large. Also we'd have to strip out
many characters (and newlines).
FEATURE: 120749, 120773
