playing movies. It can be very useful when using desynched subtitles.
A new command 'sub_step' is added, which takes an integer argument.
'sub_step +1' will immediately display the next subtitle, adjusting
sub_delay as if one had used the 'sub_delay' command to navigate to
the subtitle. 'sub_step -1' displays the previous subtitle and
adjusts the sub_delay. By using these two commands you can navigate
among the subtitles without having to search blindly using 'sub_delay'.
