* 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.
* This module more or less crashes every region in the instance if you enable it by moving it from local /bin to global /bin
* But hey, it crashes in lots of interesting ways.
* See OpenSim.ini.example for more details
* The old sqlite/mssql settings were redundant and effectively ignored anyway. Hence, there's no need for you to change your current settings, which will still work
* In fact, asset_database should probably be moved to [Network] since it's meaningless for standalone installations
* DelinkFromGroup was removing the parts from the delinked group, which later upset the update thread when it tried to do a queued update for that object
* Temporary fix is to stop deleting the parts, though it would be good later to stop sending out the now spurious updates
* This fix actually reveals another bug, where rapid linking and delinking will cause the non root prims to disappear (though they're actually still there if you relog). This is the next bug to tackle.
* Terrain Area-of-Effect brushes now should work properly.
* Updated the scale / effect of various brushes. Small & Medium brushes should now actually do something.
* This is in order to identify whether it is these which are somehow causing the massive texture packet bloat,
* since this is the only other packet put on to that queue other than the TextureSender ones
* Added osSetPrimFloatOnWater(BOOL) to make Physical prim float at the water level.
* osSetPrimFloatOnWater(TRUE); or osSetPrimFloatOnWater(FALSE);
* By default, prim do not float at the water level.
* More work is needed on the floating, but it's a start.
* W.I.P: Hydraulic Erosion (Spherical) paintbrush - code is all there, but some work is required on the initial parameters to get it to function correctly. Replaces the smooth brush when `newbrushes` is switched on.
* Implements the Optimised Erosion routine defined by Jacob Olsen in the paper 'Procedural Terrain Generation' (http://www.oddlabs.com/download/terrain_generation.pdf)
* Replaces the 'flatten' brush when 'newbrushes' is enabled.
* Added "script terrain newbrushes <true|false>" to enable experimental terraforming brushes. Presently the 'revert' brush is replaced with the Weathering brush, when enabled.
