Version 45 - Tackle that centre!

I'm going to get the centre of the map feeling right, so I think drastic measures are in order.

Experimentation with new layout, removed ramps as I feel that was contributing to the 'large yet cramped' feeling of the centre area.

Extra platform around inside of centre.

Added a tall wall to the centre to make it feel imposing.

Map not playable: centre in re-build.
