[MPlayer-dev-eng] gui: subtitle menu is not populated when playing from mpg file

[Lode Leroy]

please consider the following fix for mplayer -gui...

mpctx_get_global_sub_size(guiInfo.mpcontext);
is not returning the number of subtitles, because
void update_global_sub_size(MPContext *mpctx)
was not called to update it.

ps: the indentation is not optimal to keep the patch size minimal
