Add Groundpound powerup (#43)

* Create Groundpound powerup * Add sounds and effects * Tweak config * Add usage note * Add screenshake * Tweak config * Groundpound punch/juice Add custom effect Play different sounds Rework damage calc Buff knockback on props * Some magic numbers as variables + Increase terminal dmgmul, 25 > 75 + fix terminal radius * More fixes, + comment * Add cooldown to fastfall start sound * Fix comment * Use a less generic name * Use a less generic name; use poroper effect file structure * Fix killicon * Create the effect ourselves * Localize * Style * Use local * Split into separate functions * Localization not really needed here anymore * Fix nil * Fix inverted logic * Cut particle amount in half --------- Co-authored-by: StrawWagen <[email protected]>
