Subject: * 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.
