TPAC: Redo some margins/padding for better collapse behavior

In the "results header", we have both buttons and form elements. In
order to have these elements collapse in an orderly fashion, they need
to be exactly the same size. To accomplish this, let's simplify and
redo a few of the element margins and padding.

At the very least, this will make the elements line up better
vertically when viewed at the normal screen width.

TPAC: Remove needless divs from results header bar

In the current state of the TPAC, these "div"ider elements were
completely invisible, yet nobody seemed to miss them.  It wasn't
altogether clear what the divisions meant anyway, so rather than fix
them, let's just trim them out for now.

Also, get rid of a useless clearing div while we are at it.  I could
not detect a valuable display difference in current Chrome, Firefox,
or IE9.
