* 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.0.6.0-stable
