Title: pliers.exec child process inherits parent's stdio (fixes #10)

It seems like the only way to convince the child process that it is in a TTY is to get it to inherit the parent process' stdio. You can't do this with `child_process.exec` ([whether it is a bug or not](https://github.com/joyent/node/issues/4691)) so I have switched to using `spawn`.

The caveat of this is I can't figure out how to also buffer only the output from the child process in order to pass it to the `pliers.exec` callback. I have commented that test out, so probably don't merge this if that's a desired feature.
