Random messages in the "Automatic messages" module

An extra option on each page (hourly basis, daily basis, cronjobs) where you can activate random messages.
You can then add as many messages as you want (with a limit somewhere, of course) and the bot will not send a specific message at the specified time, but will select one at random.
This could be useful, for example, for servers who want to send a different (random) message every morning in the chat to increase activity (always the same message is also a bit boring in the long run).
