* Documentation for load/save xml methods

* Insert the very rough beginning stubs for a save/load OpenSim archive facility that will load/save prim assets (textures & inventory) as well as the prim details themselves 
(our existing xml facilities).
* This won't be ready for even rough testing for quite some time.
* I'm doing this directly in the region server for now since this will be quicker to get something working (hence giving me the Serotonin boost that I need).  However, there are 
very good arguments for later also including it (or moving it entirely) to the separate export executable which Sean stubbed out some time ago.
