* Completed DeRezDestination enum Simian: * Added IInventoryProvider to allow other extensions to create inventory items * Basic derez support for deleting items (the new inventory items in the trash won't actually work because the assetID is meaningless until we have an IAssetProvider) git-svn-id: http://libopenmetaverse.googlecode.com/svn/trunk@2175 52acb1d6-8a22-11de-b505-999d5b087335
