    appNotifications: Add line wrap for simple notifications
    
    When a command output is too long, they are not readable on smaller
    screens. For example when you type /TOPIC command on a channel with
    a very long topic, the notification is printed as one line and not
    readable. Adding lineWrap to the notification labels properties makes
    the label printed out as multiple lines and all of the output is
    readable this way.
