Add Parachute tool

[DrewBritt]

Getting the parachute back in would be nice. I'm noticing a lot of noobs tend to take fall damage before they learn about how far they can fall, so having this tool & auto-deploying it if the player is to take fall damage would help give feedback without punishing the player too harshly.

It would also be nice to get crates/barrels to deploy with these, as slowing the fall down a bit would allow:

1. More stable spawns in regards to physics, which should hopefully help spawns bouncing off the map
2. Allow us to pan the camera on them when they spawn, giving more feedback to the player in regards to their existence
