Add verbose to options

[rkesters]

The user can now have a verbose key in the options object of the jshint setting in their grunt file. This setting will be passed to the reporter. Unit test cases are also included. Example config below.
Fixes issue #208 and #210

jshint: {
            all: ["**/*.js", "**/*.json"],
            options: {
                globals: {
                    logger: true
                  ##},
                esversion: 6,
                sub: true,
                expr: true,
                ignores: ['./node_modules/**/*.js', './node_modules/**/*.json'],
                reporter: require('jshint-stylish'),
                verbose: true

            }
        }
