[tex4ht] \LaTeX and \TeX logo in the HTML output

[Michal Hoftich]

Hi all,

I know there were some requests to use plain text output for \TeX and
\LaTeX commands in the past. Finally, I've implemented this as the
default version for the HTML output. The fancy version that try to
mimics their appearance in PDF using CSS can be requested using the
"fancylogo" option.

Best regards,
Michal
