This is an experimental patch that adds support for comparing texture

hashes for the purpose of accurately responding to AgentTextureCached
packets. There is a change to IClientAPI to report the wearbles hashes
that come in through the SetAppearance packet. Added storage of the
texture hashes in the appearance. While these are added to the
Pack/Unpack (with support for missing values) routines (which means
Simian will store them properly), they are not currently persisted in
Robust.
