Subject: [PATCH] [media.mpv] Made the event API compatible with all python-mpv
 versions.

The format of the `MpvEvent*` classes, the data passed to the event
callback and the available event type enum fields have all changed
between python-mpv < 1.0.0 and >= 1.0.0.

This change makes things work with all mpv + python-mpv versions.
