Remove spawn-sync dep

[wesleytodd]

Is it possible to remove that dep in favor of using the built in one?

I understand backwards compat issues, BUT let me tell you my story:

I am using the linter happiness (a fork of standard). I added it to the package.json's of my company modules, about 100 of them. We are also using linklocal for development and a recursive link via bulk. Turns out that the npm install in all these directories takes like an hour. Here is the dependency tree that is leading here:

node_modules/happiness/node_modules/happiness-format/node_modules/esformatter/node_modules/npm-run/node_modules/spawn-sync

spawn-sync is a c extension, so gets compiled for every npm install that is run. I didnt spend the time to figure out how many times it is run, but I started it at like 9am and now it is 12 and it is still running :)

I had some time, so figured I would open an issue here.....
