Title: RFC: Quaternion rewrite/refactor

This is the first step towards resolving #963.

- Incorporates #948. Made some efficiency related improvements to the setLookAt() method and also added a member version.
- Continues, consolidates and homogenizes the work from #950
- Removes the change from #957 (thus fixing #961) based on the example set forth by libGDX
- Makes no efforts towards #920.

Future efforts can resolve #920.
