* Added CoordinateFrame class for camera management * Added NetworkManager.OnSimConnecting that blocks before connecting to a new sim * CurrentSim no longer goes null in between teleports * Applied jradford's patch to fix the DeedObject patch * UDP socket Bind() is used instead of Connect() now and sender verification is done in PacketReceived() to fix an apparent compatibility problem * Added Helpers.VecCross() for vector cross products * TextureEntryFace and TextureEntry now implement ICloneable git-svn-id: http://libopenmetaverse.googlecode.com/svn/trunk@1384 52acb1d6-8a22-11de-b505-999d5b087335
