Pass path to config.json as argument

Great work on the module. Really dig its simplicity. Small improvement request: being able to pass the filename of the config.json file. I have so many other stuff in the root of my project, and it would be great if we could change it. Other than that, love it!

@laurentvd Honestly, I was considering moving the config.json parameters into package.json. The only issue I see there is protecting the login credentials.

In the mean time it shouldn't be difficult to add the config filename as a configurable parameter.

Agreed. I think encouraging users to protect their credentials is a good thing. Maybe even suggest to put the default config.json in .gitignore and add a config.example.json to the VCS.
