read package.json and npm-shrinkwrap.json by default?

[pdehaan]

This is my current boilerplate for grunt-nsp:

module.exports = function (grunt) {
  grunt.config('nsp', {
    package: grunt.file.readJSON('package.json'),
    shrinkwrap: grunt.file.readJSON('npm-shrinkwrap.json')
  });
};

Not sure if there is an easy way to just default to package.json and npm-shrinkwrap.json by default if they were not specified. It seems like this would be the 98.3% use case anyways. (I think this is how grunt-nsp-shrinkwrap worked too.)

I think default behavior would be nice to have. I would probably default it to loading package always and if it can find a shrinkwrap to load that as well. Seems like it would catch most situations.
