- rewrote Windows console code for Windows 10's new terminal.

Browse source 
This allows dumping a lot of shit code using deprecated Windows functionality and bringing the code in line with Microsoft's roadmap for terminal/console functionality.
Note that this will cause garbled output of non-ASCII characters on Windows 7 and 8.1, but proper handling on these declining systems is of far lesser importance than future-proofing the feature.
