Removed some uses of printf in libbu++, I would like to get rid of all of them

some day, but I'm not in much of a rush, I just wanted to do a quick survey.

Also added the Formatter::flush special stream value, so now you can do a:
  sio << "hello" << sio.flush; and it'll flush output immediately.

I also tweaked a few things in the cachestore and cache so that they actually
throw exceptions and the like instead of just printing out some garbage.
