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!
