Gui

• Trying to close a window will first close any opened drop-down. This improves navigating drop-downs with controllers.

Bugfixes

• Fixed intro sound being treated as gui effect instead of music. more
• Fixed that LuaFluidBox::get_fluid_system_contents() did not behave correctly when the fluid box was not part of a fluid system.
