Use a headless terminal to save an 'image' that is sent on connection

[gulrotkake]

Terminal state is currently not saved and sent to new connections. For example when connecting to a terminal where something is being drawn, mid-draw, the result is half of the drawing. A solution to this is to have the server render the terminal in a headless terminal emulator and send this rendered image to the client on connection.
