Title: Added extend self to Helpers module

I wanted to be able to use the helpers in a Resque job without including the entire module. The way I use it is

```
Url2png::Helpers::Common.site_image_url(url, :browser_size => AppConfig.thumbnails[:browser_size], :size => AppConfig.thumbnails[:size])
```

Just a small change to make the helpers a bit more helpful :)
