Can't turn off debug logging

[bmcallis]

Debug logging is always on for bots, regardless of the debug flag.

It appears that this is the problem code

    self.out.debug = function() {
        if (!this.debug) return;
        util.log.apply(util, arguments);
    };

this.debug is that function, so it's never falsey which means that the log always happens. I believe that checking self.opt.debug instead will achieve the desired results, but I'm not sure if that's the "right" fix.

Oh, huh. I thought I did a test for this somewhere to make sure it didn't randomly debug, but presumably I haven't – oops.

I seem to have a name clash, between the function debug and the debug boolean I set in the initialization: https://github.com/Throne3d/node-irc/blob/master/lib/irc.js#L102. It should be a relatively quick fix, and I'll try to get to it soon. Thanks!

Should be fixed in 3eff8bf.
