Thread:Feedback/UI issues

Minor UI issues:
 * "bump this thread" has wrong tab order
 * clicking "watch" over a thread will erase the watch link instead of changing into unwatch or giving some other form of meaningful notification
 * if you open multiple comment textboxes, the text in the earlier ones is lost
 * all comments have a subject field when edited. They don't seem to have any useful effect; changing only the subject field has weird results: the edit will be logged in the thread history but not in the comment history.
