* Fixed 'flatten area' brush, so it now has a 'force' instead of instantly flattening the selected area.

* Noise, and Noise-Area brushes now use Perlin noise, more closely simulating the method LL uses officially.
* TerrainModule has been cleaned up slightly.
* TerrainUtil class has several new functions related to seeded noise generation.
* Extracted ITerrainEffect, ITerrainFloodEffect, ITerrainLoader, ITerrainPaintableEffect, TerrainChannel to seperate files.
