Adds features to support default file descriptor redirects for the target process: 1. A new command line flag '--redirect' and '-r' are added to specify file redirects for the target process 2. New syntax is added to the 'restart' command to specify file redirects. 3. Interactive instances will check if stdin/stdout and stderr are terminals and print a helpful error message if they aren't.
