Add "appearance rebake" command to ask a specific viewer to rebake textures from the server end.

This is not as useful as it sounds, since you can only request rebakes for texture IDs already received.
In other words, if the viewer has never sent the server this information (which happens quite often) then it will have no effect.
Nonetheless, this is useful for diagnostic/debugging purposes.
