Add basic magic teleport plugin for standard spellbook

[charles-m-knox]

This is a very simple and standalone plugin that enables standard spellbook teleports. It further fleshes out the existing magic teleport plugin.

Features:

• supports air, fire, water, earth staffs (but not multi-element staffs at this time, though i suspect it wouldn't be too hard to implement)
• grants xp
• plays the teleport animation and sound
• prevents the player from moving during a typical teleport animation

Other notable changes that were required in order to implement this:

• level-up dialogue is now shown 1 tick later than the tick in which it occurred
  • without this change, the dialogue occurs on the same tick as the teleport, which misbehaves.
  • OSRS processes the level-up dialogue 1 tick later as well
• adds player.metadata.castingStationarySpell and a player.canMove() check for this that prevents walking during spell casts; open to suggestions on a better spot for this if there is one

Looks great, we should probably swap out the itemIds lookup with keys, but its fine
