Posting messages with new line (\n)

[lrodriguezwatsco]

Hi, i'm using your plugin, so far so good, Thank you. But, when i try to post a message like
url => "https://hooks.slack.com/my_hook"
channel => "my channel"
username => "user_name"
format => "%{environment} \n%{level} \n%{user_id}"

the message is post correctly but, looks like: local \nerror \n2. instead of
local
error
2
Thanks
