Camera module

[kennux]

Implement a UnityTK module with helpful stuff for setting up generic game cameras:

• [x] Static cameras
• [x] Top down cameras
• [x] Isometric camera
• [ ] "Fake" Isometric camera (Perspective low FoV, far away)
• [x] (Investigate) 3rd Person Camera
• [x] (Investigate) 1st Person Camera

Generic features:

• [x] Shaking (Spring physics?)
• [ ] Waypoint movement (Scripted and static in scene)
• [ ] API for modifying camera properties (FoV, projection matrix, ...)
• [ ] Focus object (constantly look at and limit user input)
