Subject: First round of a task framework.  Tasks are job definitions stored in
 the database.  They're started with admin/maintenance/start/[task_name] which
 sends down some JS/HTML which regularly pings the task at
 admin/maintenance/start/[task_id] until its done.

The UI is still very rough.  It works, though!
