Stomping was guarded by the invincibility check, so during a downward dash the player could never deal stomp damage. Move the invincibility guard to only protect against taking damage, not dealing it. Extend dash invincibility by PLAYER_DASH_INV_GRACE (0.15s) past the dash duration so the player is briefly protected after landing. Closes #15
