refactor proxy_read - avoid the ugly `goto copy' to jump back to the start - avoid leaking memory

parse response MIME, check the charset and lang If the charset is not UTF-8 nor ASCII then we don't know how to handle the body and so rejects it. An abset charset is implied to be utf8, so we're good. In the generated HTML we always use UTF8 charset, which is fine too, since it is a superset of ASCII. Attempt also at saving the lang for later reuse in the generated HTML.

include a footer with the original URL

inline images
