Chii: !vote doesn't remove temp-vote [DONE]

[wahaha]

... !votetmp should preferrably also refuse any new votes once a permanent vote has been cast.

[pelican]

For that matter, can we have a method for explicitly revoking votes temporary or permanent (for those little mistakes, especially with anime ids) added to the irc interface?

[Elberet]

Yeah, maybe voting 0 could be translated to removing the vote.

[wahaha]

"!vote r" would be more consistent with the existing "!vote <new> r"
