[Opensim-dev] No more inventory downloads -- yey! (Re: pruning reference servers in core)

Remember, the command is:

git clone git://github.com/diva/Diva-s-OpenSim-Tests.git

The worst part is that it'll put it into a directory called
Diva-s-OpenSim-Tests.git/ .  You can rename it.  (or, perhaps someone
more familiar with git can suggest a way to not have to rename it?)
