Cumulative update: pagination + footnote

Changes done on the Controller.php to enable pagination, and to posts index view so that it would properly display pagination.

makeView() must be adjusted because now there are two modes of input: has pagination or without pagination. When there is pagination present (usually when consuming from makePostList()), it would adjust the data structure accordingly. The behavior for input without pagination is solely for backward compatibility of other views.

As an addition, a default footnote is also added. Customization of footnote is pending.
