Give option to honor system theme

[GoogleCodeExporter]

I really like gnome-mplayer but I find it very bad etiquette to override the 
gtk3 system theme to a dark one without giving any option to turn off this 
intrusive behavior. I use adwaita and even qt apps look less alien to my 
desktop than gnome-mplayer.

Just following the example of Totem for this behavior. If you are willing to 
recompile the code, you just need to removed the following line from main.c

g_object_set(G_OBJECT(gtk_settings), "gtk-application-prefer-dark-theme", TRUE, 
NULL);
