Added -nojline CLI option to emulate vanilla console behaviours. Added JLine disabling compatibility (removes the '>').

-nojline disables JLine, removes the '>', sets the timestamp to vanilla's and sets the language to English.

-Djline.terminal=jline.UnsupportedTerminal disables JLine and removes the '>'.
