/SET force_colors -> /SET term_force_colors. Added /SET term_scroll_fast
option to specify if we want to scroll with fastest method, or the cleanest
method. The default is cleanest and it looks best with xterm, with some
other terminals where line-by-line scroll is slow, you might want to use the
fast scrolling.
