vo_opengl: use low quality default settings, add opengl-hq alias
Change the default settings for vo_opengl to highest performance and compatibility, but lowest quality. Use bilinear as default scaler. Add "opengl-hq" as alias for high quality settings. This alias uses exactly the same settings as vo_opengl did before this commit.
