Title: Added support for grunt template stings.

Template strings in grunt will allow you to easily include values from other files. Below is an example of what im doing in my grunt.js file with this pull request to pull my aws settings from another file.

aws: '',
s3: {
key: '<%= aws.key %>',
secret: '<%= aws.secret %>',
bucket: '<%= aws.bucket %>',
access: 'public-read',
}

Where grunt-aws.json is just a json key:value file like package.json.
