Fix multiline chats only showing the first line

[FranciscoG]

I've already started to work on this in some places so I just need to finish it.

Right now some of the commands or events send multiple bot.sendChat messages. Plug seems to be dropping some of the successive messages and so you only ever get the first message like this

What I've been doing is just combining strings and separating them with a newline\n and only sending one chat message at the end. Hopefully that'll do the trick
