Add message on Server Join

[synsypa]

tried to add a message on server join, but didn't work. Should be useful when the bot goes down to indicate revival

@bot.event
@asyncio.coroutine
def on_server_join():
    log.info(log_msg(['bot join', bot.user.name, bot.user.id, 'server', bot.server.id]))

    yield from bot.say('yo, we in there')

    log.info(log_msg(['sent_message', 'server_join', ctx.message.channel.name]))

was my attempt

Currently, it looks like this:

What is the .next() here for?

Maybe we need something like:

    # Get all channels 
    all_channels = yield from bot.get_all_channels()

    # Iterate through channels
     for channel in all_channels:
         bot.send_message(channel, 'yo, we in there')

Oddly, can't seem to get the on_server_join() event to trigger, even when turning it on in the server settings.

I got it to work by moving it to the on_ready() event.
