Various fixes in next and top level directory

Some broken links were fixed in some of the files like next/index.html,
next/pw-change.html, next/index.html and status.html.

Some wrong images were used in next/submit.html (or at least referred to
wrong if not wrong image).

Useful update to FAQ about the answers file in mkiocccentry.

There might have been other things.

This might be all that is needed for next/ wrt the register/change
password/submit but it's possible something has slipped through.
