Fix getVPP rotation error

This is big error let positioning wrong position and can not mapping to
world coordinate. Now fixed. Thanks god!
Save orientation as float and add header for log
recalculate real distance when have angle in x axis.
change SAS size measure method

Use longest length as SAS size. This is better solution for SAS that
height is similar with camera.
Modify angle parameter for HTC ONE

After 7m rotate experiment. We found have some error for angle
parameter. So fine-tuned.
Just modify SAS_SIZE as distance for future experiment
1. rotate orientation to landscape
2. calculate final distance for better result
3. run resetStatusView if perferences set bulk mode
4. skip fused filter effect in pitch and roll
Merge branch 'temp-because-rorate-error'
change float to double in sasRelativePosition
Fix getVps rotate funciton

This is big bug too! I am not confirm and always think it's correct
before. But it's wrong. Now correct it.
fine tuned getVps to get precise vertical value
better results till now
it's works for using centerAzimuth to define SAS azimuth face
latest stable version
change textview and add prepareInfoString funciton for better debug
change distance field to sas size field
