Update to act as a Bot Account

[kkirsche]

It would be great for this to be compatible with the Bot Account structure as discussed on:

https://docs.mattermost.com/developer/bot-accounts.html

As this clearly is described as a sample bot, it is a bit confusing that it doesn't work with bot accounts due to the requirement of logging in.

If I understand you clearly. You are trying to reply message with Bot.
I have tested with v6/model. it works fine.

Step 1: Use client.SetToken
//LoginAsTheBotUser()
client.SetToken("YOUR_BOT_TOKEN")

Step 2: In HandleMsgFromDebuggingChannel , check botUser

if botUser != nil {
 		if post.UserId == botUser.Id {
 			return
 		}
 	}
