Removed unnecessary spacing from prefix from within the code, thanks @JohOply for pointing that out
Added a space after the prefix in config (you might want to add this yourselves or delete old config to regenerate it)
Added extra checks to help prevent doubled notify-on-join messages after reloading the config
Also thought I'd inform you guys that the "\n" newline placeholder works you just have to change the single quotes at the start and end of the message into double quotes and then add the "\n" to where you wish it to be
