Subject: Bug 693547: Android external hyperlink support

Paul had written code before to detect clicks on hyperlinks, but
we hadn't actually done anything with these clicks once detected.
Andre Ferreira supplied a couple of lines of Android magic to form
the Intent from the URL and execute it. Incorporate that here.
(Andre should have &eacute; but this upsets git/my editor, sorry)

As part of this patch, we now respond to links at a higher priority
than the left/right clicks to flip pages (but only if link following
mode is enabled).
