 * pagination_list_footer
 * 	Input variable $list is an array with offsets:
 * 		$list[limit]		: int
 * 		$list[limitstart]	: int
 * 		$list[total]		: int
 * 		$list[limitfield]	: string
 * 		$list[pagescounter]	: string
 * 		$list[pageslinks]	: string
 *
 * pagination_list_render
 * 	Input variable $list is an array with offsets:
 * 		$list[all]
 * 			[data]		: string
 * 			[active]	: boolean
 * 		$list[start]
 * 			[data]		: string
 * 			[active]	: boolean

 * 			[active]	: boolean
 * 		$list[pages]
 * 			[{PAGE}][data]		: string
 * 			[{PAGE}][active]	: boolean
 *
 * pagination_item_active
 * 	Input variable $item is an object with fields:
 * 		$item->base	: integer
 * 		$item->link	: string
 * 		$item->text	: string
 *
 * pagination_item_inactive
 * 	Input variable $item is an object with fields:
 * 		$item->base	: integer
 * 		$item->link	: string
 * 		$item->text	: string
 *
 * This gives template designers ultimate control over how pagination is rendered.
 *
 * NOTE: If you override pagination_item_active OR pagination_item_inactive you MUST override them both
