Improved responsive design of dynamic menus

When DISABLE_INDEX=NO and HTML_DYNAMIC_MENUS=YES (both defaults) then
on screens with a width smaller than 768 pixels, the menu will collapse into a
bar with just a hamburger button and the search field.

Also the search result window now stays within the limited of the
screen.
