Added delay command for IRC

[bolecki]

Hello! I added another command that will delay the bots response for a number of seconds in IRC. This will make the bot seem more human by simulating time to think and type.

For example, !delay 7 will add a seven second delay to the bots response. !delay 7 11 will set a range, where the delay will be a random number between 7 and 11. Set the delay back to 0 seconds with !delay 0

Thanks!

That's really cool!

For even more realism I'd suggest using

delay = random.uniform(self.settings.delay[0], self.settings.delay[1])

so that a random float is picked instead of just an integer amount of seconds.
