Added favicons to the 'URL' column. Favicons are displayed to the left of the
url, similar to how they're displayed in the omnibox.

images are displayed to the left of the contents and description, similar to how
they're displayed in the omniobx. For answers which have text associated with
them (e.g. 'weathe<b>r</b> / 76°F Thu / answer type weather'), it will be
displayed in orange after the contents and description.
