Subject: [PATCH] Added options:maxSize support, grunt log

adding in Grunt log, adding in support for options: maxSize. Grunt command would look like:

grunt.initConfig({
    inline: {
        dist: {
           options: {
                    maxSize: 65536 // default to 64KB
                },
            src: 'src/index.html',
            dest: 'dist/index.html'
        }
    }
});
