[Bug-gnubg] Small cache changes

I've done some experimenting with the cache code and ended up changing very
little o). I should have fixed the minor #Q.00 analysis output problem (so Max
you should be able to build with -O3 if you changed that).

The cache setting in the options dialog now tells you how much memory the cache
is using, I found that my sample position got notable quicker as the cache was
made larger, flattening out at about the 175mb level.

There's every chance that I may have messed up things, so hopefully someone
could give the code a quick go to see if it's ok (maybe we should have some unit
test code to check the major things are ok?). If anyone is keen enough to try
rolling out some positions with different cache sizes I'd like to know how that
