Subject: [PATCH] Bug Fix for undefined

I would get

```
   Warning: Cannot read property 'forEach' of undefined Use --force to continue.
   TypeError: Cannot read property 'forEach' of undefined
    at Object.<anonymous> (/node_modules/grunt-purifycss/tasks/purifycss.js:22:18)
   .
   .
```

and then the task would stop

looking at the grunt API I noticed that data simply returns the object value I passed in my config
which if according to the example is inside data.target not the data object itself

using grunt 0.4.5 (but I got that from the latest documentation for the API
