Having both a Content-Security-Policy (CSP) in meta tag and per header
works fine together. They are merged and the strongest one is applied.
It makes Croodle safer for all users even if the hoster does not apply CSP
for some reason (e.g. they can't set custom headers).
It's still a good idea to recommend using a CSP header cause that ones
are applied earlier - even so this shouldn't be a problem cause we ensure
that CSP meta tag is present before any other link, style or script element.
