1. Improve response by using unfiltered data from Leap library
2. Reduce distracting arm-flail by only attaching the arm to che glove when we're not in rave mode.
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
Note that the actual Leap SDK can't be in the repo for IP reasons, so there's a stub-version of the header. When the actual SDK is put into the Leap folder, cake will find it automatically and switch over.
