Added: More armor to Armor rune.

The armor rune is something that only gets used when the cult decides to kill everybody, and that's fine, but usually it's used purely for the sword and nothing else.

I've added some alternatives to the rune, while having the talisman remain the same.

"Summoner" gets the magus robes that the wizard's able to wear, and can cast some longer cooldown versions of the artificer's shard and shell spells.

"Traveler" replaces his worn space suit with a cult space suit, which has higher armor (It's comparable to the syndi RIG suit but not QUITE as good. They are antags, so I can't find anything wrong with this.)

"Marauder" is supposed to be a little easter egg but anybody who reads the code can see it, if you're wearing the captain's space suit when you use the armor rune you're given the choice of marauder, armor is the same as "traveler" but you get a very nerfed version of summon creatures. (requires cult armor worn to cast.)

The "Summon creatures" spawns 2 abominations on a cooldown of 500. It's noted as "DANGEROUS". I did test, and the marauder himself can easily kill both of the creatures if he clicks the button unwittingly.
