Description

Various exception included exit codes, specifically Shell.ExitCodeException, ExitUtils.ExitException().

If all exceptions that wanted to pass up an exit code to the main method implemented an interface with the method int getExitCode(), it'd be easier to extract exit codes from these methods in a unified way, so generating the desired exit codes on the application itself
