Double Jump

Adds a double jump to your slugcat! Not as powerful (or noisy) as Artificer's. Default keybind is the jump button, can be changed with Improved Input Config. Some properties in detail: -It can only be refreshed once with walls to prevent easy infinite wall climbs. -Cannot be used while holding a grappleworm (future to-do: allow usage if there are no conflicting keybinds?) -The double jump will have different properties depending on the directional input, listed below. Neutral (no direction) Gives good height, slugcat flips, and maintains horizontal momentum. Very strong when combined with pounces. Diagonal down Most similar to Artificer's diagonal jump (it does not send you down, it sends you diagonally up). Gives good height and momentum and makes slugcat start flipping. Horizontal Most similar to Artificer's horizontal jump. A tiny bit of vertical height and launches slugcat to the side while flipping. Diagonal up Like diagonal down, but gives a bit less height, and does not force a flip. Useful if you need to land cleanly afterwards. Up Gives most height, forces slugcat to stand upright, removes any horizontal movement. Best for verticality, or to help with precise jumps. Down Resets ALL slugcat's momentum, horizontal and vertical. Can only be used if you're falling rapidly.
