Well, the features are not really all that amazing, but the mex spots are fixed.

Changes:

- Metal points have features indicating their location
- Metal points are all +2.0 and are symmetric
- Tree hitboxes drastically reduced, rock hitboxes moderately reduced
- Rocks moved slightly to make them equidistant from start locations
- Heightmap around oasis tweaked slightly to make coast look better
- Start boxes expanded for 3v3 and up
- General modernisation of internal file structure

Tested in a bot match and it seemed to work fine, so featuring over the previous version.

The middle lake of Dune Patrol was always completely rover-pathable, but land units did move faster on the bridge in the middle.

I am not a big fan of underwater areas which look largely the same but behave substantially differently.
