Implement onReceivedTouchIconUrl.

Add DownloadTouchIcon, an AsyncTask that downloads the apple-touch-icon for urls
that are marked as bookmarks. The touch icon is stored in the bookmark database
similar to favicons and thumbnails. If a shortcut is created for a bookmark
containing a touch icon, the touch icon is used (with rounded corners).

Refactor the bookmarks query to be a static function. The function uses the
original url and new url to look for matching bookmarks. This takes care of
redirects as well as bookmarks containing queries.
