Added make run
Significantly boost the default view distance
Implement a much more efficient voxamp render layer

This uses display lists, to greatly enhance the speed at which voxmaps
are rendered (up to 122 times in the best calculated case).

It also pushes the vertex position calculations into the renderer itself.
This avoids using pushmatrix, which saves a bunch of time
Adjust the camera to get a better default position
Bump up dimensions for the demo
