player: ensure runtime updates of certain rendering options

When adding things like brightness or gamma, the video obviously needs a
redraw if paused. This happened to work in the normal case because the
OSD notification triggered a redraw, but if you use no-osd the picture
won't change. Fix this by adding another option flag, UPDATE_VIDEO, and
simply signalling we want a redraw. This gets handled along with the
normal osd redrawing check in the playloop so something like "no-osd add
gamma 1" actually works.
