#133 Fixed 'library not loaded' error on OS X

Fixed an exception on startup on OS X that would occur if you don’t
have Leptonica installed. I’ve recompiled Leptonica and Tesseract to
store their libraries in /private/tmp/HearthStats.net-Uploader so that
OS X will now look for those libraries in there instead of the default
/usr/local/lib/
