DragAero 0.2.1

• No more Keychain question after updates. DragAero kept your licence in the macOS Keychain, which asked "DragAero wants to use your confidential information" again after every update. The licence now lives in a private file in your user Library. You may see the question one last time while DragAero moves the licence over.
• This is also the first update delivered inside the app: from now on, new versions arrive through DragAero → Check for Updates… and install with one click.
