lilypond-manuals.css: edit color scheme and some spacing

This patch simplifies and (IMHO) improves the color scheme
and spacing of the manuals on the web. I will include a link to
screenshots and a demo site, with more details on what's
different.

Here is a screenshot showing the language section in the footer. See reitveld issue for more details and link to demo site.

Paul, I've been thinking for some time that language selection should be moved to the top, for the following reasons:

1. It's the place where most people expect the language selection to be. There are obvious reasons for this.
2. Add to previous argument the fact that links in online manuals are nice links without extension and the browser always serves the file matching the browser language setting (issue [#2273]). So if you happen to use a browser in a language different from the language you'd like to read, you'll need to scroll down each new page to select the right language in the footer.

Obviously, this belongs to a new issue. But I'm curious to know your opinion.

Hi Federico, I'm not opposed to that, in principle. I think the devil is in the details of how it's done, but it's only one line or two of text so that's promising... (I think it would require changes to the code that generates the html, which I think is in Perl, which I don't know.)
