So...I've had one person suggest using html_no_css (default off)
instead of html_use_css (default on).

I was intending to keep the current option and just turn it on by
default, so that there were no surprises to people currently using the
option, but I'm not sure whether this is really necessary.

If I keep the existing option, and just turn it on in the plugin, a
user could override it by:

1. using a "-c" command-line option
2. putting a VimEnter autocmd in the .vimrc
3. putting a file in the after/plugin directory
4. manually calling unlet g:html_use_css before generating the html

But this is less convenient than just putting "let g:html_no_css" in the .vimrc.

I would like to avoid that someone who has g:html_use_css in their
.vimrc gets surprised when they unlet the variable and nothing
happens. I'm leaning toward using both options, defaulting
g:html_use_css to true, and overriding it if g:html_no_css is set. I
could certainly be convinced to use just one or the other if there are
good reasons to do so.
