Provide replacement strings from content_profile

It's very common on sites which use UR to have content profiles for each user using the content_profile module.

In those cases people's real (full) name is often the title of those profile fields.
It would be nice if you could use the fullname because people sometimes choose weird usernames which leave the requestee in the dark about the identity of this person.

However, this data is not available as replacement string in the request message template (see screenshot).
