Artnet 2 Twinkly 3.13.8 is here

3.13.8.0 Enhancement: 

1.  A perfect json backup/restore of a device or group layout directly from the grid.  Perfect backup only works while logged-in but it works when the device is off-line.

2.  Export a virtual grid to a json array. 

3.  I also border the main preview bordered in grey so you can see the actual preview area.

4.  You can once again pick your starting universe.  Some devices expect it to be zero.

Also some various bug fixes.
