Title: Attitude Estimation & Quaternion Update

Updated implementations of attitude and quat modules.

attitude:
- Added start/stop method to standardize with other modules
- Exposed pose quaternion getter function
- Slightly improved implementation of attEstimatePose to return faster when there is no motion

quat:
- Improved implementation of quatNormalize to reduce number of float divides
- Added argument copying to quatMultiply so destination can also be operand
- Added quatCopy method to copy quaternions
