Add class to Edit Idea link.

[BoweFrankema]

A small change to the templates so that an icon can be easily added to edit links.

Thanks a lot @BoweFrankema It may be a surprising workflow, but i like to have master === latest stable tag and i do my edits on a new branch and just before releasing the plugin i merge the new branch with master. So would it be possible to pull this request on branch 2.3.1 instead ?

• for this particular case, as it's possible to completely override the plugin's post type to use the plugin to manage something else than ideas, i think it's best to use something like this :

$class = 'edit-item';

$labels = wp_idea_stream_post_type_register_labels();
if ( ! empty( $labels['labels']['edit_item'] ) {
   $class = 'edit-' . $labels['labels']['edit_item'];
}

return '<a class="' . sanitize_html_class(  $class ) .'">';
