Make HTML Help files display a font-size change button on the toolbar.

I had no idea that was a thing HTML Help could do at all, let alone
that .chm files could enable or disable it via a flag! But Tino
Reichardt sent in a patch which sets one extra bit in a flags word in
the .hhp file, and despite 'chmspec' not mentioning that bit at all,
it does indeed seem to do something useful.
