* Refactored Environment/Modules directory - modules now reside in their own directory with any associated module-specific classes.
* Each module directory is currently inside one of the following category folders: Agent (Anything relating to do with Client<->Server communications.), Avatar (Anything to do with the avatar or presence inworld), Framework (Classes modules can use), Grid (Grid traffic, new OGS2 grid comms), Scripting (Scripting functions, etc), World (The enrivonment/scene, IE Sun/Tree modules.) * This should be moved into a seperate project file.
