Thanks to a recent commit, the translation files will now
have info about locations where the string is used. That
can help is deciding the correct translation, as all contexts
are more easily found.

"Content-Type: text/plain; charset=UTF-8" was wrote twice in each
of base.po and firewall.po, and one was an incorrect place which
was the cause of the errors.

And, The escape in abbr HTML tag was incorrect, so I fixed it.
