From 9c98c9243d9cc8b495dce4ef15ed0df94c8d0df5 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Use TerminalConsoleAppender for console improvements

Rewrite console improvements (console colors, tab completion,
persistent input line, ...) using JLine 3.x and TerminalConsoleAppender.

New features:
  - Support console colors for Vanilla commands
  - Add console colors for warnings and errors
  - Server can now be turned off safely using CTRL + C. JLine catches
    the signal and the implementation shuts down the server cleanly.
  - Support console colors and persistent input line when running in
    IntelliJ IDEA

Other changes:
  - Server starts 1-2 seconds faster thanks to optimizations in Log4j
    configuration
