Use ResourceLoadPriority type in the NetworkCache code and rely on ResourceLoadPriorityHighest value instead of hard-coding a new maximumRetrievePriority constant. This seems a bit more robust.

The way to do this cleanly would be to have NetworkCacheStorage::setMaximumPriority (or constructor argument) and call it from the NetworkCache.
