Adds telescopic riot shields

- HoS shield (the one that spawns in his locker) replaced with telescopic shield
- More can be made from research (they're very pricy though, and start in lockboxes)
- Buffed force of riot shield bashing
- Lowered throw range of riot shield
- Increased throw force of energy shield when activated (captain america!)
- Changed e-shield so you can throw it further and faster when it's deactivated

Telescopic shield:
- Identical stat-wise to normal riot shield
- Collapses like an e-shield for easy storage in backpacks
- Fits on back as well if carrying your shield on your back is your kinda thing
