Force delete of expired users

[timwhite]

We already have cron functions to delete users who have run out of data or time (and aren't expired). It would be good to have an easy way to force delete all expired users, regardless of how long ago they expired. Useful when using low expires like a week. Otherwise the accounts can stick around for awhile.

Would also be good to make these buttons in the interface, and instead of cron functions like they are now, make it a configurable option that cron picks up
