More small -Thtml improvements by kristaps@,

in particular, use <B>, <I> and <U> where appropriate.
Provide relative widths for header and footer lines.
Manuals: More concise short descriptions of output modes.
Correct a few places still talking about CSS2 to say CSS1.
Code examples should use .Dl, not .D1.
