Title: Allow images' URLs to be prefixed with anything

This will allow pulling images from a different domain, like requested in #11

Just define the prefix in `_config.yml` like this, without a trailing slash:
```yaml
image:
source: assets/images
output: assets/images
url_prefix: http://yoursecondarydomain.com
```
