    Add Ctrl-f and Ctrl-b for pagedown/up in varnishstat.
    
    This adds another vim-style key binding to varnishstat.
    
    Couldn't find any good way to extend u00008.vtc to test it. The
    cursor is always at column 22 and page-downing to the bottom
    will break the test case when we add another counter.
