Aufwind Glider Tracker Hack 1.2.1 + Redeem Codes

Fixes the missing gliders. Sorry about that.

This update contains many small improvements and sets the stage for good things to come.

This update adds icons for static objects and contains other small improvements.

Thanks for your positive feedback so far. This update adds the much requested feature to favorite some aircraft. I also added the option to limit the length of flight trails and an experimental AR mode where you can see the aircraft in AR, albeit with some delay from to the OGN network.
