Avoid redownloading CLUT when reloaded.

Browse Source 
In Brave Story, the game reloads the CLUT frequently, but doesn't actually
render to the CLUT that often.  It also switches between a few different
rendered CLUTs - so caching that we've downloaded is a HUGE win.

In case someone reading this message is interested, it actually renders
these CLUT tables from what appears to be a color wheel.  Crazy huh?
