Have less shallow water, more deep water

Delete a bunch of old code from previous attempt at map generator

Copy over "narrow shelf" and "isolated 1 tile of shelf" terrain tiles from CTP1 to CTP2... though interestingly I believe they were never used by either game due to how their map generator works

CTP2 trench rule missing for NW shelf wall

If the height map generates a deep water tile next to land, we have to override it and force it to be shallow water, or the terrain tiles can't draw it

Code was incorrectly converting shallow water into continental shelf, should be converting deep water into continental shelf

Get rid of constants for special scenario tiles

Now I'm not using the CTP plasma generator, there's no need to use their skewed coordinate system either
