Added "save-prims-xml2 <PrimName> <FileName>", as we were lacking a method to save a single primitive or small group of them. This command will save all prims in the current scene that name matches the "PrimName" parameter. The saved file is in standard xml2 format, so can be loaded using load-xml2
