/*
* A walker class to use that extends wp_dropdown_categories and allows it to use the term's slug as a value rather than ID.
*
* See http://core.trac.wordpress.org/ticket/13258
*
* Usage, as normal:
* wp_dropdown_categories($args);
*
* But specify the custom walker class, and (optionally) a 'id' or 'slug' for the 'value' parameter:
* $args=array('walker'=> new SH_Walker_TaxonomyDropdown(), 'value'=>'slug', .... );
* wp_dropdown_categories($args);
*
* If the 'value' parameter is not set it will use term ID for categories, and the term's slug for other taxonomies in the value attribute of the term's <option>.
