Updating Stratux.

Stratux .sh updates can be used to update Stratux in three ways:

1. Auto-update via an EFB (WingX or Aerovie Reports).
2. Download an .sh update from Releases. Upload it via the web interface (http://192.168.10.1/, "Settings").
3. Inserting the microSD card into a PC/Mac and creating a folder "StratuxUpdates" on the "boot" partition that automatically mounts. The same .sh file from #2 can be copied here, and the update will execute the next time Stratux is started up.
