* The main page's title appears in search results, so use "The Racket
Language" instead of "Racket". Additional minor tweaks to a few more
titles to make them presentable as search results.
* Add a `#:description' keyword to make it easy to add it to pages. Add
such texts to the main page, downloads, community, learning, people,
and mailing list pages.
* Add a <meta name="robots" content="NOODP" /> to the front page, to
avoid getting the ODP (dmoz) blurb, hopefully the new and improved
description(s) will be used instead. (If not, this should be
reverted.)
* Add a reference from the community page to the bug reports page.
* Make it possible to subscribe to lists right from the community page.
Improve the email input boxes with placeholder text and a short
explanation on hovering.
This covers all of the html files in mailman's template directory, and
we should have a consistent look for all pages. (Including archived
messages.) Also tweak the front page to have a link to the mailman
"listinfo" page with the complete list of the hosted mailing lists.
Ie, the difference between using it as a language and as a module is now
the same in both. Also, improve `scribble/html' (and
`scribble/html/htmllang') by reproviding most of the corresponding text
modules.
Change `meta/web' accordingly, and improve code by making a new langugae
(`#lang meta/web'). This language is similar to `scribble/html' except
that it uses the plain scribble reader (not the `-inside' one), it
doesn't use the customized module-begin feature (that uses
`output-xml'), and it adds all the relevant bits of `meta/web/common'.
(Also, "meta/web/common.rkt" is gone, since it's used only as a language
now.)
This commit has lots of details and binding games, so it's tricky, and
potentially caused some problems. (Took me a while to track many
breakages, so I won't be surprised if there are more.)
