SH-3041 WIP Utilizing early object update texture data

Caching the mapping between baked texture hashes and UUIDs should be
able to be avoided if the initial texture data sent down is accuate.

This patch will use the first objectupdate message sent for your own
avatar to set the baked texture UUIDs for your avatar. These appear
to match the UUIDs sent from the hash lookup.

Testing needed to verify that you can successfully decloud before
the server sends you the hash lookup response, if your bakes are
cached locally.
