The "classic" theme is a mostly useless wrapper around the basic theme
that just adds a collapsible sidebar (that we no longer have).
Moving to basic directly drops a layer of indirection and a file that
needs to be transferred over the net.
Same thing goes for "default.css" which literally just includes
classic.css (WHYYYY???)
(also this removes some useless javascript)
This used to put the TOC last, which is the last place you'd want it.
It's not perfect and we do some hacky layoutery to achieve it, but it
should generally be usable.
Released under the Python Software Foundation License, this one
doesn't look awful (no green top bar, huzzah!).
Lightly forked it to remove the donation footer (we don't take any)
and to change the python references to fish references.
The image is just our favicon, which is a stylized "f" and therefore
not fantastic (are we facebook?), but it's the best I found, and the
thing before had no images at all.
Fixes#6500
(as far as I'm concerned)
