There is still at least one nasty bug, I will have a look at it when I have 
the time for it again (next couple of days).

It wouldn't be a good idea at all to cache it, and the decompression algorithm 
is already quite optimal at least in the aspect that it's pure C++. Low level 
optimization would make sense here, but that has to wait until the more 
important things are done. Keep in mind: how many compressed gigs are out 
there? Not many...
