Improvements and fixes

Remote access stops asking you to log in again, Q-reader reactive energy stays complete, and string orientation is worked out correctly at more plants.

• Reaching an older device's own web page through remote access no longer asks you to log in over and over.
• Your reactive energy readings from a Q-reader meter are no longer dropped when the counter moves down.
• String orientation is now worked out with few clear days, on days with an hour's gap, and where inverters sit at their limit around midday.
• A string whose own orientation cannot be measured now uses the orientation of its inverter, instead of being left out.
• Without a panel datasheet you still get wiring, connections and orientation, only not peak power; with no strings set up the analysis says so.
• Your combiner boxes, irradiation sensors and feed-in meters now show the data logger they are read from.
• Adding a data logger now says why a test read fails; a Zebotec needs only its address, inverter banks and sensors read from it.
• Security updates for third-party components.
