this is step 2 of 2 of the OpenSim.Region.Environment refactor.
NOTHING has been deleted or moved off to forge at this point. what has happened is that OpenSim.Region.Environment.Modules has been split in two: - OpenSim.Region.CoreModules: all those modules that are either directly or indirectly referenced from other OpenSim packages, or that provide functionality that the OpenSim developer community considers core functionality: CoreModules/Agent/AssetTransaction CoreModules/Agent/Capabilities CoreModules/Agent/TextureDownload CoreModules/Agent/TextureSender CoreModules/Agent/TextureSender/Tests CoreModules/Agent/Xfer CoreModules/Avatar/AvatarFactory CoreModules/Avatar/Chat/ChatModule CoreModules/Avatar/Combat CoreModules/Avatar/Currency/SampleMoney CoreModules/Avatar/Dialog CoreModules/Avatar/Friends CoreModules/Avatar/Gestures CoreModules/Avatar/Groups CoreModules/Avatar/InstantMessage CoreModules/Avatar/Inventory CoreModules/Avatar/Inventory/Archiver CoreModules/Avatar/Inventory/Transfer CoreModules/Avatar/Lure CoreModules/Avatar/ObjectCaps CoreModules/Avatar/Profiles CoreModules/Communications/Local CoreModules/Communications/REST CoreModules/Framework/EventQueue CoreModules/Framework/InterfaceCommander CoreModules/Hypergrid CoreModules/InterGrid CoreModules/Scripting/DynamicTexture CoreModules/Scripting/EMailModules CoreModules/Scripting/HttpRequest CoreModules/Scripting/LoadImageURL CoreModules/Scripting/VectorRender CoreModules/Scripting/WorldComm CoreModules/Scripting/XMLRPC CoreModules/World/Archiver CoreModules/World/Archiver/Tests CoreModules/World/Estate CoreModules/World/Land CoreModules/World/Permissions CoreModules/World/Serialiser CoreModules/World/Sound CoreModules/World/Sun CoreModules/World/Terrain CoreModules/World/Terrain/DefaultEffects CoreModules/World/Terrain/DefaultEffects/bin CoreModules/World/Terrain/DefaultEffects/bin/Debug CoreModules/World/Terrain/Effects CoreModules/World/Terrain/FileLoaders CoreModules/World/Terrain/FloodBrushes CoreModules/World/Terrain/PaintBrushes CoreModules/World/Terrain/Tests CoreModules/World/Vegetation CoreModules/World/Wind CoreModules/World/WorldMap - OpenSim.Region.OptionalModules: all those modules that are not core modules: OptionalModules/Avatar/Chat/IRC-stuff OptionalModules/Avatar/Concierge OptionalModules/Avatar/Voice/AsterixVoice OptionalModules/Avatar/Voice/SIPVoice OptionalModules/ContentManagementSystem OptionalModules/Grid/Interregion OptionalModules/Python OptionalModules/SvnSerialiser OptionalModules/World/NPC OptionalModules/World/TreePopulator
