Subject: Tweaked the cache format, it's no longer compatable with the old
 version, but it is less than one tenth the size, without using anything as
 slow as a compresion system, I just store each string only once (it's sort of
 compression).

I also updated the plain viewer to not be so annoying if it doesn't have
anything to do.
