0.9.2 and tests

So I decided not to release 0.9.2, even if I tagged it in git.. I
tried to fix some minor bugs, and now I have just commited a slight
change in the way booh-classifier loads data. It should allow for
faster "large moves" (moving tens of images in a row by keeping an
arrow key pressed) and above all, is supposed to fix some crashes
during large moves on some platforms.

If you use booh-classifier, you may want to test latest git. Tell me
if you have errors with it.
