nit: indent this to line up with "The path..." on the line above

I think this still needs clarification. In particular, it should be clear that
for "normal" most visited items, this param will be empty (even though a normal
most visited item will have a "locally stored" icon in the favicon database).

Let's be more explicit here and call this the "whitelistIconPath" and describe
it as "The path to the icon image file, if this is a whitelisted most visited
item. Empty otherwise." Also, could you update all the other places in this CL
to say "whitelistIconPath" instead of "largeIconPath"?

Done.

      * @param offlineAvailable Whether there is an offline copy of the URL available.
      * @param index The index of this item in the list of most visited items.
