This changeset is the step 1 of 2 in refactoring
OpenSim.Region.Environment into a "framework" part and a modules only part. This first changeset refactors OpenSim.Region.Environment.Scenes, OpenSim.Region.Environment.Interfaces, and OpenSim.Region.Interfaces into OpenSim.Region.Framework.{Interfaces,Scenes} leaving only region modules in OpenSim.Region.Environment. The next step will be to move region modules up from OpenSim.Region.Environment.Modules to OpenSim.Region.CoreModules and then sort out which modules are really core modules and which should move out to forge. I've been very careful to NOT BREAK anything. i hope i've succeeded. as this is the work of a whole week i hope i managed to keep track with the applied patches of the last week --- could any of you that did check in stuff have a look at whether it survived? thx!
