Engine:
* New weapon attributes: ejectX/ejectY: Offset to the hedgehog (center of hand graphic) where the projectile(s) will be spawned
* Changed Laser Sight to origin from the weapon instead of the hedgehog (needs some adjustments while walking/jumping)
* Changed most weapons to no longer shoot from the hedgehog's center and use the weapon's visible position instead (might require some testing and adjustments)
* Silenced the small Piano explosions
