More robust terraforming tools.

[raqubits]

I can't imagine this would be high up on the priorities (or how difficult it would be to implement), but having some more tools for shaping the map would be great, like a terrain smoother, ruler, or multiple sizes of mountain pen. (Or perhaps more options in the map generator for mountains, craters, and plateaus?)Obviously it's possible as is to make a great map, but the limited amount of options currently in the game can make it a tad inaccessible when it comes to making scenarios. It would be nice to see a few more so even more custom scenarios show up (and to make creating a good one less painstaking)!
