v0.8.67

Asked by a user with an AMOLED screen, which must not show the same picture for hours: a screen timeout for glass-evo, since it turns off the kiosk's own. Glass's half; glass-evo does it from its 0.1.35.

• "Screen off after, minutes" in the look panel. In the Backgrounds section of "How the screen looks": the minutes with nothing playing and no touch after which the screen glass-evo holds goes black; 0, the default, never. A tap wakes it and is the wake alone, and music starting wakes it too. It is the face's setting face.idle.off, kept with the look, in a face theme [idle] off.
• The screen's pixels go dark; a panel's backlight is not touched. On an OLED that is the screen off; on an LCD it is a black picture.
• Not yet: a slideshow when idle. The picture when nothing plays (0.8.63) stands still; a show of several is a later stage.
