Issue Summary

Currently, the characters in the CAPTCHA image are all in the same font.

Adding the possibility to have the different characters in different fonts would raise the bar for automated attacks. For humans on the other hand, the difficulty would not increase that much, I think (this largely depends on the choice/mix of fonts of course).
