Remove some link rel from meta.inc?
In meta.inc, there are some links like:
<link rel="home" href="@@HOME@@index.html" title="CMUCL Home Page">
<link rel="banner" href="@@HOME@@doc/" title="Documentation">
AFAICT, the rel
values are not valid. Maybe we should just get rid of them.
https://developer.mozilla.org/en-US/docs/Web/HTML/Link_types lists the valid types.
