Amiga: Add "cut" option; make cut/copy/paste menus context sensitive; allow dragging

selections within NetSurf window to text fields (does not work across windows).

todo: switching tabs will reset cut/copy/paste menus to initial state; cut option is
putting something on the clipboard which causes a crash when pasting it back
