[PR] Replace teleport scroll and Soulguard with Flee spell

[LeahTheTech]

I quite like soulguard as a good way for newer players to lose some of the stress of getting immediately killed. If the issue is the clunky interface then why not just change the scroll to teleport back to the wizard den immediately, since they can then use the computer to get anywhere they like. Although frankly I'm not sure wizards need to be able to get away more reliably anyway.
