CH-901 by Zarabadoo: Add qtip tooltips to statistic table headers.

Is this just because we are using it right now with table column headers?  If so, perhaps it is better served in something specific to the A/B report rather than the generic?  Of course, we could just cross that bridge when we come to it and just add a quick note.  And then there is the case that I just have complete misunderstood ;-)
