Subject: * 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.
