Send a message to the seller of a Kleinanzeigen listing (UNTESTED draft).

UNTESTED until recorded logged in. Sends the user's message to the seller of one Kleinanzeigen listing from the user's own logged-in account, after an explicit Allow that shows the listing title and message. Uses the listing page's own contact form (CSRF token from the page). Some categories ask for extra fields (e.g. postcode); those are not supported yet.
