acrefoot 7a97d01719 Fix broken viewport.message_viewport_info() calculations ...

`#tab_bar_underpadding` overlaps some with `.message_header`,
so adding `#tab_bar_underpadding.bottom + .message_header.height`
gave us a nonsense message viewport top.

Doing the calculation this way is more robust, as long as:
1) `$(".floating_recipient").offset().top` continues to give us a sensical number
   and is the last element just before the top of the viewport.
2)  nothing appears between the composebox and viewport.

In this commit I also removed the other couple of places where the #tab_bar_underpadding
was being used as a viewport reference, that no longer makes sense.
