enhance: add first/last buttons for block-nav, no wrapping (#1015) (#1016)

Browse source 
Added 2 new buttons (only visible in block-nav mode), with new icons and new (en_US) strings (First/Last Difference).
Implemented these new buttons, and disabled the automatic wrap-around for the prev/next buttons in block-nav mode.
