Don't redirect when redirector launches itself

[rockerbacon]

What it does

Fixes #387 by using a new environment variable NO_REDIRECT.

When NO_REDIRECT is set, the redirector will run the original game launcher instead of MO2. The redirector will add NO_REDIRECT to the environment before launching MO2, ensuring that all further executions within the environment will launch the game launcher.

The solution works perfectly for the specific issue it aims to solve. There are small caveats that might be encountered in the future:

• Processes launched by MO2 may unset NO_REDIRECT. The likelihood of a process doing this is near 0.
• The current argument forwarding logic was left unchanged, which could break processes attempting to pass more than 1 argument to the game launcher. There's currently no known process that attempts to launch the game's launcher with arguments.

Additionally Includes

• Fix for wide character strings not being properly logged under Windows/Wine
• Debug binary's terminal will now wait for user input before closing, allowing developers to more easily read crash logs
