/*

Shows the latest incoming *Direct Message* (DM), as well as sender.
This complements the threaded message applets

This module doesn't collect its own text message. Instead, the WindowManager stores the most recent incoming text message.
This is available to any interested modules (SingleMessageApplet, NotificationApplet etc.) via InkHUD::latestMessage

We do still receive notifications from the text message module though,
to know when a new message has arrived, and trigger the update.
