This commit change sthe "OK"-link to dismiss the cookiewarning bar
from a link to a POST-based form, so that non-JS users are able to
click it, too. If clicked, the dismiss is saved int he user prefs
(if the user is logged in) or in a cookie.
The JS version still works without reloading the page.

de i18n message now represents the en translation. The mobile opacity
is now 1, instead of 0.85 from desktop (it covers text in mobile, which
makes it harder to read with the opacity).
The URL isn't hardcoded anymore, it now can be configured with a config
option.

Enable the CookieWarning to be visible on a mobile device (bottom, instead of top).
Instead of only rely on cookies to save, that a user accepted that we use cookies,
save it as a user preference, too.
