Implement MapBoundsPlacer that returns all points on the tilemap.

Browse Source 
Use it to replace the hacky resetTerrain rmgen2 function from 6d52a71d4a
and initHeight from 280a797620.

Highlights that createArea is the primary tool of rmgen, rather than
nested for-loops over the mapsize.
Neglect that the heightmap grid is one tile larger than the tilemap grid
for now.

This was SVN commit r20894.
