Reimplement Special:MoveThread with the new HTMLForm interface, fixing several bugs...

* Bug 18949 LiquidThreads allows threads to be moved to pages without LiquidThreads enabled.
* You could move a thread to the page it was already on, which would leave strange placeholders that don't make sense.
* Allowing wikitext in some new places where it makes sense.
