Used for the newcustomimage_modal actions

The .data('recipe') value on the outer element determines which
recipe ID is used as the basis for the new custom image recipe created via
this modal.

Use newCustomImageModalSetRecipes() to set the recipes available as a base
for the new custom image. This will manage the addition of radio buttons
to select the base image (or remove the radio buttons, if there is only a
single base image available).
