Votewiki has a lot of test elections in the interface which is confusing for election admins as well as voters. We should clean out the old test elections once they have outlived their usefulness.
- Add an "archive" link to the main securepoll page
- The link sets a flag that archives the election
- Current elections shouldn't be archivable (should not yet happened elections?)
- Archived elections shouldn't show on the main page
- Only users in the election admin group should be able to archive
