Improve HQP Title Scoring

Improve HQP Title Scoring

I was not satisfied with how difficult it was to get reasonable scores for quite long page titles even when multiple words contained in the title were typed so I added a limit on how much of the title (and URL) string was required in order to have a decent match.

BUG=None
TITLE=Ran all unit tests.

This may be a second, separate review of the same change you have received. If
so I apologize and ask that you go ahead and review this CL as the prior one
seems to have been lost in the transition of my chromium.org account.

OK

I got two OKs but no LGTM and the commit agent barked at me. How about an LGTM?
