added a request interface for timed quiets
added an anti-spam plugin for irc flooders

Configurable to quiet a user if they say X messages in Y seconds with a
customizable message and a customizable duration.
misc changes to Owner plugin and wotd plugin

added !code as an alias for !source. Or the other way around, I forget.

Changed so the bot doesn't kick if you say the word of the day as the
entire message, if it's a repeat of someone else. The kick on repeat
was just meant to catch people saying the entire line that happened to
accidentially trigger it.
Merge branch 'master' into py3k

Pulling in the latest master changes before I do much more conversion on the 3k
branch
last couple changes to get it working on py3k

One twisted module used is not completely finished porting, but the
function used is, so the import in plugincontroller is adjusted.

Changed "str" to "bytes" in irc.py, which should have been done by 2to3
but I guess it missed it.
