[1/2] Base: Volume panel timeout

PS: If volume panel is displayed in expanded mode,
        ignore the custom timeout duration and use
        the default timeout of 3000ms.

PS: make timeout setting stick on reboot. derp.

PS: if user sets volume panel mode to expanded always,
        custom timeout will apply to it.
