Title: Changing representation of sampleTimesIndex in the SceneCache

I've managed to get 13% faster frame rate on our simple crowd scene by representing the sampleTimesIndex as a IndexedIO::Directory as opposed to a double entry (which had to be reloaded everytime it's queried).

The changes keep read compatibility with previous saved files.
