Cannot cancel and reapply

I've tested Job Search, patched as per http://drupal.org/node/391774#comment-1777452.

It might happen that a user applies to a job, than cancels the application in a hurry since something was forgotten.
In that case, however, it becomes impossible for the user to apply again, after fixing whatever needed to be fixed, since the system will say "you already applied for this job" even after cancellation.

I believe the condition should be reset if the cancellation originates by the original applicant, so that a new application can be made at a later time if needed. Alternatively, or in addition, a confirmation page would really be useful during the job application process.
