updating options to be loadImage.scale compatible

The issue appears when using `processQueue` to upload multiple image resolutions.
When using `imageCrop` option, the image are just scaled, not cropped.

```
{
  action: 'resizeImage',
  maxWidth:  cfg.photos.width,
  maxHeight: cfg.photos.width,
  imageCrop: true
}
```

That's because JavaScript-Load-Image is using `crop` option and jQuery-File-Upload is sending `imageCrop` option instead.
