Automated redirect for old post/thread links

The vb import process tries to do things in a very clean way and because of that assigns a new post id/thread id starting at zero. It does preserve a concept of an import ID. I had written something to update all of the postID/threadID's to the old numbers but the one sticking point was threaded mode. Due to the way the parent/child post setup in vb works there was no easy way via sql to update the posts without breaking the parent posts used for threaded mode.

So instead I took some code from the vb import author and extended it a little.
