Subject: [PATCH] Windows builds log to goldencheetah.log when not debugging
 (#3485)

Similar to Linux/macOS builds, messages are redirected to goldencheetah.log
when not output to console is requested, but instead of relying on low level
stderr redirection a message handler logging directly to the file is installed.
