Camera update and adding Chris's first pass pipes
Added a bit of air alignment
Adjusted camera vals
Basic (Broken) Split Screen.
The UI scene is set up with two players rendering to a different part of the screen. It still doesn't work well because both players are controlled with the same input.
I've also cleaned up some of the placeholder items now that we have actual items in each of our folders.
Reworks Input Manager to Work With Split Screen
There are now mappings for P1 ... controls and P2 ... controls. Any new input mappings should be done in this manner.
The audio listener was also removed from the player prefab since it will need to manually moved around the screen so audio for both players can be picked up.
Player cam++, weapon and model

- Cam angle better
- Cam zoom feels like a shooter
- Player always looks towards cam forward
- First pass model implemented
- Placeholder eapon points to cam forward
Fully Refactored Controls for Split Screen
The controls for split screen are no longer all messed up and janky. Player 2 doesn't have input at this point, but player 1 can be controlled as normal.

Merging Changes
CWade created a player prefab on his working branch, too, so I merged them together. The player prefab should now have everything we need for both players.
