Bug 30069: (QA follow-up) Rebase and add filter

This patch now checks the status of messages and ignores any message
with a status of 'new'. It is also rebased to account for changes made
to cleanup_database.pl in bug 17350.

Test plan:
1) Ensure you have some EDI orders or even just some dummy messages in the edifact_messages table with a mixture of statuses including 'new'
2) Run perl misc/cronjobs/cleanup_database.pl --edifact-messages 100 --verbose (Change the number of days according to the data in your table)
3) The response should show a number of messages that would have been deleted
4) Run perl misc/cronjobs/cleanup_database.pl --edifact-messages 100 --verbose --confirm
5) The response should now show the same number of messages have been deleted
6) Check your edifact_messages table to confirm that the data has been deleted
7) Confirm that no messages marked 'new' have been deleted
