Improving cult

* Narsie now converts floor tiles by changing their icon, rather than using changeTurf()
* replacing a hundred of /red with <span class='warning'
* fixing Teleport talismans not working
* the Teleport Other rune now actually swaps the objects and mobs between the two runes rather than just sending them from the touched rune to the other.
* added animations for the Summon Cultist rune and reduced the self-inflicted damage of both this rune and the Free Cultist rune (Because sending 3 cultists into crit to summon one sounds a bit wonky to me, take_overall_damage ain't no joke)
Hopefully this won't be too performance-intensive.
