ActiveLook support

Support for glasses with HUD - https://www.activelook.net/

• First install the official ActiveLook application and update the firmware of the glasses
• This is an early release; you can expect some problems, please report, especially when you are able to replicate the issue
• The non-Pro users can use the built-in layout (which will likely be subject to change in future releases), Pro users can build their own layout in a similar way as normal XCTrack pages
• Currently only one 'page' on the glasses is supported
• When widgets overlap, the top one with at least some data wins; all widgets that are under an active widget are hidden
• You can overlap more text widgets, use the widget settings to hide both title and value when no data is available
• The glasses can reasonably display only english texts; the events are directly in english, all other text are converted to ASCII
• The sensor on the glasses provides hand-motion sensor and ambient light sensor. According to the docs it is supposed to consume up to 50% of the available energy. The hand-motion sensor is not implemented in XCTrack, you will probably save a lot of energy when you disable Auto brightness (you will likely set the brightness to max anyway)
• The refresh interval is set to 1 second. There is not much bandwidth available between the glasses and XCTrack.
