v0.8.71

Reported on the forum: a theme's button with button.nextmeter.action = meter.next "changes the skin on the computer (FACE) but does not simultaneously change the skin on the RPi."

• A meter stepped to in the Manager's Face tab is shown on the player's screen too. A meter.next or meter.previous button pressed on the screen already moved the Face tab and every remote that follows the player; pressed in the Face tab it moved that page alone. The page now hands the meter to the plugin (POST /api/face/meter), the plugin asks the player's own display for it over the channel ({"kind":"show","meter":"..."}), and the display's answer brings the other views along. The display shows it when the theme on show has a meter of that name, and its own next step goes on from there. With no display of the player's own running, the page keeps its meter to itself as before.
