Title: Ignore data-src when src is real image.

If both data-src and src are present, and src is set to something other
than holder.js (or other configured domain), leave the image untouched.

Someone using holder.js in a CMS template can then easily set just the src of the image instead of rewriting the entire image tag to override the holder.js fallback. Example:
```php

/>
```
