FEATURE: More Variant Swatch Display Options

Added a few extra settings to the Product Details theme settings to customize the display of Variant Swatches. Also moved them into their own group in the Product Picture Settings area.

The Settings will allow you to choose the width of the swatches to resize to, the max number of columns to display as well as whether to display to the right of the dropdown or below it.

This will make it easier to enable swatches and have control without having to manually add the merge to each Variant Group's footer HTML.

Default Display (maxcol=10, width=15) This is what is currently displayed when simply checking the Show Swatch Next to Variant Option box.

With Max Columns set to 3, Width set to 50, and set to show Below:
