Adds a three-second cooldown to the alien hunter pounce

Does as the name implies. I was inspired to make this after a round on Sybil in which one alien hunter knocked down an entire deathsquad. Pounce is still viable, but far less spammy.
Make another toggle please.
Like another toggle button appears if "leap" is on, and that changes between "Continuous leaping" and "Pounce"

because I Hate the idea of forcing the player out of leap mode, constantly having to toggle to it.
