Minor tweaks to the cache object base class. The per-object mutex is actually
in the CacheEntry class, not the CacheObject, so you can't lock it until you have an entry. This isn't a big deal unless your objects aren't actually part of a cache yet. I changed it so that lock/unlock have no effect if you haven't joined to a cache yet, probably not ideal, I'll think about moving that mutex. I also fixed it so you can lock/unlock even when const.
