@crhultay This is great work, thank you!

One note on the color: Please use the existing pipe code based system already in use in code such as in connect.js via pipeWrite()

pipeWrite() is an extension of ClientTerminal; however the code I have written is to console.{level}.

Looking inside of client_term is a call to renegateToAnsi().

Do we need to write a new extension to console.prototypes? (not entirely sure how to do this in JS).

Edit: If you show me how I could initialise a ClientTerminal that would be used by the console when Enigma1/2 loads -- this opens up some interesting possibilities... like the callawait screen.

@crhultay Sorry, yes just use renegadeToAnsi() and process.stdout(). Note however, that some may be running this in environments where ANSI is not suitable, or capturing in logs -- thus, you'll want to respect NO_COLOR and/or a --no-color type CLI option, which makes this more complex.
