title: Set channel id for DiscordBot for multiple servers
body: <p>Could someone help me set command to set channel for specific server 
  so that it does not interfere with each other? Actually I have this:</p>
  
  <pre><code>var testChannel = bot.channels.find(channel =&gt; channel.id === "hereMyChannelID");
  </code></pre>
  
  <p>I want to set command which Owner can use to set channel id for his server.</p>
