dropped simulated gyro support. Maybe will be restored in the future.
Refactored SensorFusionManager (fix sensor not unregistering).
Fixed wrong snapshot orientation in Capturerenderer on some devices
(Nexus 5).
Don't know what was the bug, and don't know ohow I solved it. Seems gone
by itself. It's magic!
fixed autoshoot not working well after onPause()
CaptureView now starts with yaw disabled for the first shoot. 
By the way, the user have to take a first shoot to start capture,
thusletting the sensorFusion to have time to calibrate.
A lot of cleanup / mess up everywhere.
added "moved "getSnapshotDistance" into Snapshot class
alternative target placement working.
