Subject: * Implementing first of the 0.6 IClientAPI Changes * Introducing
 IClientCore - this will be the key replacement for IClientAPI in the long
 run, it has a very minimal set of methods designed to allow you to access
 specialist API's. * See
 https://lists.berlios.de/pipermail/opensim-dev/2008-September/003049.html for
 the early discussion on this.
