Energy Net Fix

I've implemented a fix for the energy net, it's a little hack-ey, but
nothing horrible. The original code set your anchor to one, which means
you can't be pushed, pulled, or grabbed. The coder seems to have assumed
it also restricted your movement, and it does not. So I set the affected
mob's weaken to 300, which is more than enough to let the energy net run
it's course. And reset it to 0 in the event the net is broken or
completes the teleportation. I also removed the inability to kidnap mobs
without a player in them, because it's a pain in the ass to test things
like this when you need a second player to help you with it.
