Presently, thread deletion is in poor shape.

1/ Special:DeleteThread is a shambles, with lots of inline HTML, it's got hacked-in support for undeletion, and it looks nothing like the real deletion form.

2/ Deleted threads still exist for the purposes of the pager.

3/ Deleted threads still have their 'root' Thread-namespace pages, which are readable by anybody.

PROPOSAL:
Instead of implementing a front-end for deletion, link to the regular deletion page, hook the actual deletion and do the DB updates afterwards.
