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/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/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
