Channels added after the bot started not recognized

[NilsKrause]

Small bug where the bot does not recognize channels that were added after the bot has started.
Happens because the 'gatherChannels' function only get called once when the bot starts.

discord.js has an event 'channelCreate' and 'channelDelete', so it should not be a problem to track channels in realtime too.

Will implement this in the next pull request.

This can also be addressed by serching the channelID dynamically.

channel = msg.guild.channels.cache.filter((channel)=>{ return channel.name === channelName && channel.type === 'voice'; });
var channelID = "";
if(channel.size == 0){
    util.print(msg,'',"There is no such channel. Maybe you made a typo?",'red');
    return;
}else if(channel.size != 1){
    util.print(msg,'',`I have found ${channel.size} channels with the same name.\nPlease rename the channels so I can select the correct one.`,'red');
    return;
}else{
     channelID = channel.first().id;
}

With this, there's no need to have a Collection of channels, neither a gather function.
In this code I have asume that I'm searching for voice channels only and also forcing the user to have unique voice channel names.
