Error messages on windows are unreadable

[w23]

This was developed on Linux so it expects a functioning terminal to write reports/error messages to.
On Windows it just opens a terminal window, that is immediately destroyed if there was an error.

What needs to be done, options:

• display errors in MessageBox
• write log file
• don't open terminal window -- it's VERY bad for perf (lol Windows)
• in-engine console ~
