[beta 4] user tags on wall post (profile post) -- xenforo import

So when upgrading from xenforo to Woltlab, the user profile end up having some raw bb code. For example, @[8949:@Wanderer] as shown in the highlighted screen shot below.

This will either need to be stripped OR user tagging extended onto wall post. I'd be happy to have them extended, but I imagine the quicker and easier solution during the import would be to strip them.
