HOTFIX: ExternalImaging Swatches

The Variant Swatch merge code ##VARIANTPICMATRIX[...]## will now support ExternalImaging as well as DirectReference images no longer forcing the Resizer.

If using ExternalImaging it will use the Thumb Base Reference to make the image.

This means that it may require CSS to resize the images if using either of these Photo Handling methods such as:

.varpicmax_img { width:50px; }

Because the width parameter in the merge will no longer apply since not using the image sizer.
