Fun (not) with fonts

Running SBBSCTRL on Windows 11 with a 4K monitor looked horrible.
The default font sizes varied widely - I'm not sure why this wasn't
apparent before now. And the default font ("MS Sans Serif") is no longer
included in modern Windows versions, so when choosing a Log font, the
pre-selected font was just blank. So change use of "MS Sans Serif"
everywhere to "Microsoft Sans Serif" which appears to have been around since
Win95 and be the preferred alternative. I would consider Segoe, but that
wasn't introduced into Windows until Vista and I'm not sure (yet) what
troubles that might introduce. I'll experiment with a WinXP VM maybe
and find out.
