Unfucked axis rendering

- Updated to have axis with interleaved data
- Reorganised shaderInit to be clearer and more lock step
- Renamed location names and shader uniform name u_mvp
- Hid QT test so I could see the axis behind it. lol
- Cleaned up old comments from shader class
Merge remote-tracking branch 'origin/master'
