Fixed broken unit tests. Shouldn't let these things go so long...
Version bump to 0.2.0
Added mailer support in failure cases. Required a bump in ayl version.
Added exception handler around the pool.reserve call and added delete job if an exception occurred without decay.
Had to fix the test after we added a delete on the non-decay path.
Had to bump the version of ayl because I botched the original release.
Merge branch 'job_delete_exception'
Regenerate gemspec for version 0.2.0
