Title: 	 Hooks for consistency with writepanel-product-type-variable.php

variation-admin-html.php already allows filtering the variation dropdown descriptions in metaboxes. No such hook exists in writepanel-product-type-variable.php to take care of the variation descriptions in the Default Selections dropdown.
