Fix spelling errors as reported by the spellcheck action

Only comments and display strings are changed here.

Notable here is the correction of referer => referrer.
"Referrer" is the actual spelling; "referer" was a misspelling
that made it into RFC 1945 (see 1).

It makes the most sense to use "referer" when referring to the
HTTP header, and "referrer" when referring to an actual referring
page.
