"vines", "plants" faction gives immunity to kuzdu (#18540)

* "vines", "plants" faction gives immunity to kuzdu

Adding "vines" and "plants" to podpeople's factions only makes them
immune to the snare of the venus human trap. Now added some checks to
spacevine.dm which checks for vine immunity, and a check in
mob/living.dm (apparently).

Podpeople (and venus human traps) are now no longer damaged,
poisoned or obstructed by space vines. Explosive vines still damage
them, because there's an actual explosion.

* Some grammar fixes for venus human traps

* Fixes compile error

* Pod people are now vine immune, completely
