New Feature:
* Repository struct field for IsFsckEnabled (default true of course)
* Admin Settings section on repo options page, accessible only by
admin users
Possible Enhancements:
* There's no way to force running health checks on all repos
regardless of their IsFsckEnabled setting. This would be useful if
there were an admin API or dashboard button to run fsck immediately.
