#8 Highlight search text in preview pages

[Peter Warden]

It would be useful to obviously mark the terms the user searched for
where they appear in the preview. One way of doing this would be to add
text formatting, eg bold, or font size+2. Google does something similar
with their cached pages, it might be good to follow their precedent,
though I don't find it always as obvious as I'd like.

Scrolling the window to show the first search term would be good too.
That needs some investigation to see if it's possible,
