People Search: View former employees

[cpabbot]

Combine the show Alumni option with a view of former employees to show all former members of Gordon. This would be useful for alumni to be able to look up a professor that retired since they have graduated, for example. Things to think about are whether we should include both faculty and staff in this view, and whether this would look like

1. changing the query if former employees are still in the Account table but simply have showAccount set to false/0
2. create a new formerEmployees table similar to our Alumni table
3. combine the two views and change the name of the Alumni table to something like FormerMembers
