* Fix metalclips

- Fixed a bug limiting the metal clip count to one

* Improve MetalClips

- Fixed bug where shooting at a block spawned two clips
- Added ShootCooldown and CrushCooldown
- ShootCooldown only applies to shooting clips
- Changed how crushing works:
--- Removed old style and variables
--- When controlling an entity with 4 clips, the controller can click to
cause the armor to "crush" and damage the entity.
--- Has own cooldown, default of 2000 (2 seconds)
- Changed launching
--- Works with all clip amounts except 4
--- When the user releases sneak, the entity will be launched at varying
power depending on how many clips were attached.
- Changed ability cooldown to activate only after the ability is
finished.

* Add CrushDamage option to MetalClips

- Fixed MetalClips bug caused in magnetizing
