Changing deletion to behave like spiking.

"Spiking" is now called "deleting" to all users. Deleting a swarm
behaves like spiking used to: it hides it from view. (It's very
similar to 'acts_as_paranoid').

That would suggest I should possibly move to acts_as_paranoid.
Adding acts_as_paranoid gem
Moving from spiked scopes to paranoia gem.

This replaces all the #spiked and #unspiked scopes. We're using the
paranoia gem to add a #deleted_at method and field. A tad of magic
but I think it's a reasonable trade-off for not having to always
type #unspiked.
