Bug 704690 - Scroll on in-page links [r=Cwiiis]

Browse Source 
Force a viewport update to Java when there is an in-page
navigation, as this will change the scroll coordinates.
This includes splitting the existing sendViewportUpdate
function into two - one that does the update and the other
that just does the send.
