Updated Link the cover image on listing/results pages to the Item

Per this suggestion: Updated - Link the cover image on listing/results pages to the Article

I've updated the 'list_view_layout' and 'grid_view_layout' macros in the 'xa_sc_item_list_macros' template, so that the cover image (whether its an attachment thumbnail or category image) links to the Item.

I've also updated several other SC templates that display a cover image/icon.
