[turba] search returning the source among the results

[liamr@umich.edu]

I guess this is a feature request.. it would be cool if one of the columns you 
could display (as configured $_prefs['columns']) was the source['title']

Soo... if you got a page listing the results from multiple searches,  you could 
tell where that particular result came from.

It's not in the same namespace that $_prefs['columns'] is looking at, so I'm 
not sure how to get it in there.
