* Added InventoryItemFlags, which is actually only the upper half of the Flags field for inventory items. Stores slam bits, permission override flags, and other things we don't use at all right now

[Simian]
* Initial task inventory support. Move, remove, and RezScript are not supported yet
* SimulationObject Frozen and RotationAxis properties now point to the root prim in the linkset
