* Added packet helpers for FetchInventoryDescendents and RequestInventoryAsset * Added a fourth parameter to BuildPacket(); byte flags, allowing the flags to be set for a packet during construction * Modified all the packet helper routines and slaccountant to use the new BuildPacket() routine git-svn-id: http://libopenmetaverse.googlecode.com/svn/trunk@43 52acb1d6-8a22-11de-b505-999d5b087335
