Honor using bot.memory, heretics one vote per user

honor.py
   Using bot.memory['honor'] for honorable and bot.memory['dishonor'] for dishonorable phrases.

heretics.py
   Only allowing one vote per user. This involved changing the structure of bot.memory['heretics'], so I am using bot.memory['heretics2'] for now. The old structure was:
    bot.memory['heretics'][<target>] is an integer

   The new structure is:
    bot.memory['heretics2'][<target>]['yes'] contains a set of nicks that have condemned <target>
    bot.memory['heretics2'][<target>]['no'] contains a set of nicks that have defended <target>
