Mark cat as inside/outside when they "look through"

[amokrunner]

Seems like since there are two coils, we should be able to mark the cat as inside or outside when they look through without actually going through. Case: cat is outside and you bring your cat in through another door, but the cat still shows up is outside since they didn't come in via the flap. Cat later looks through the flap, it should get marked as inside by that event, since we know it must be inside.

that would be neat :)
