	* You can now see your own messages you've typed on slack/mattermost web in irc
* irc: Add PasteBufferTimeout option (send ascii-art!)
   	* See matterircd.toml.example for an example.
   	* PasteBufferTimeout specifies the amount of time in milliseconds that \ 
messages get kept in matterircd internal buffer before being sent to
   	 mattermost or slack.  Messages that will be received in this time will be \ 
concatenated together
   	 So this can be used to paste stuff like ascii-art or code.
   	 Default 0 (is disabled)
   	 Depending on how fast you type 2500 is a good number
