fixed FOV preference to work with view frustum code properly
(changed per requests and re-merged) Two Leap-related crashes fixed, plus Leap improvements
1. Fixed thread-crash at terminate() time by terminating the LeapManager properly
2. Fixed an intermittent thread-crash when Leap active by removing auto-connection between controller and listener
3. Added fingerRoot positions to display and data packet
4. Introduced a vec3-based convention so that more finger data may be added without causing trouble for old clients and servers
5. My avatar's fingers are different color from others
