manpage: remove examples and authors section

The examples demonstrates use with optical media, which is far from
mpv's main purpose.

The authors section is a leftover from MPlayer times. There are enough
other places which reiterate how mpv is based on mplayer2/MPlayer,
copyright statements, and so on.

 Note that mpv likes to mix ``/`` and ``\`` path separators for simplicity.
 kernel32.dll accepts this, but cmd.exe does not.
