Hierarchal Entity local positions.

- Entities now use local positions. This allows hierarchal movement.
- Pins still use world positions, with the exception of the Absolute
Local pin, which uses local positions.
- Absolute Local pins now mirror properly.
- Added config file to allow easy tweaks to OS localisation.
- Minor visual adjustments.
- Added quick hack to hide 1-frame delays by running 2 update loops per
draw cycle.
