TerrainPerlinNoise

This Editor wizard generates the terrain heights from a perlin noise function. Access it by clicking on the "Terrain/Generate from Perlin Noise" menu item. There is only one option, tiling, which affects the tiling of the perlin noise functions. Increasing the tiling increases the number of hills. I didn't add an option for height for this simple script, but if you feel you need it it should be pretty straightforward to add.
