Added a default signal handler for SIGINT (Ctrl-C)

Added a default signal handler for SIGINT that does the following:
- Terminates a pipe process if one exists
- Raises a KeyboardInterrupt for other parts othe code to catch

Also:
- Changed the default value for quit_on_sigint to False
- Modified the way the subcommand functions are called in subcommand.py (unrelated to rest of commit)
