The presence of stdin doesn't necessarily mean there's an allocated tty. This breaks watch mode in non-TTY stdin contexts (e.g. docker, foreman, etc). A simple process.stdin.isTTY check would theoretically be enough but unfortunately, subprocesses don't have the same API, which are used extensively to test via calls to `spawn`. A simple solution is to inject an env var dependency where we tell the process that it's indeed a TTY-allocated process and so, watch mode with exit handling is good to go.

@0xradical I assume c58170c was mistakenly pushed here? |

Otherwise, code looks good, but I want to test it out a bit before I merge. |

A more robust but also annoying solution would involve using an actual terminal emulator (like Microsoft's node-pty). Though the environment gets exponentially more difficult to setup since it
involves compiling bindings, which require different requirements per OS.
Closes #424
