Title: Add support to exclude files from file.expand

Since the globbing utility runs per entry separately, thus destroying minimatch's ability to exclude items prefixed with `!`, I added the support into grunt.file.expand

```
Filelist:
a.js
b.js
c.js
```

```javascript
var files = grunt.file.expand(['*.js', '!c.js']);
// results in:
// [ 'a.js', 'b.js' ]
```
