It turns out that Qt font selection via style name is broken on
Windows (QTBUG-101436). As we use our own style name for discriminating
our math fonts and applying proper kerning, we need a fallback method.
With this commit we check for the family name when the style name does
not match. In computing the kerning we also consider the right bearing
reported by the font instead of the width of the enclosing bounding box,
as this produces better results (see bug 13087).
Fixes#13087.

Each token could be delimited by quotation marks or not. The previous
regexes only considered this for two tokens and hence produced wrong
matches for cases such as
\Format gnuplot "gp, gnuplot, plt" "Gnuplot" "" "" "" "vector" "text/plain"
where the extension list wasn't parsed as a single token.

Previously, the tooltip was assigned during updateBuffer. But then
we could not determine the value for forward references.

There are several reasons to do it this way, among which is odd
behavior of the TOC filter if we put anything else there. This also
allows for filtering of the references themsevles in a natural way.
The change, I think, was really an unintended consequence of other
changes connected to showing formatted references in the work area.
