grunt-iife's Issues

Small issue with grunt file

Hello @virtyaluk, you have a nice plugin here, congrats. I get small issue with grunt.file.exist, I did a research and I finding in http://gruntjs.com/api/grunt.file and the correct function is grunt.file.exists.

But I not know if this issue is because the version of grunt.

grunt iife                                                                                                                                                             
Running "iife:dist" (iife) task
Warning: grunt.file.exist is not a function Use --force to continue.

See my module:

module.exports = {
    dist: {
        files: {
            './src/scripts/chip.js': './dist/scripts/chip.js'
        }
    }
};

You can tell me where I mistake?

Indentation of code

Hello again, the result is great but not indented, the linters show errors with the indentation.

;(function() {
'use strict';

/**
 * Chip
 */

angular
    .module('xx.chip', [
        'ngSanitize'
    ]);

    ...
}());

Try check with JSHint, ESLint, JSCS...

Compression option

First of all thanks for the great Grunt plugin! We have been using it in many projects.

We currently require to modify the output manually to achieve better compression. For example, it is possible to create a IIFE using !function(){}() which would save some extra bytes.

If you would ever want to improve the plugin, I hereby want to suggest to add a compression option including unary_operator option.

!function(){ /* code */ }();   // returns true by default
~function(){ /* code */ }();   // returns -1 by default
-function(){ /* code */ }();   // returns NaN by default
+function(){ /* code */ }();   // returns NaN by default
