Copyright in AppData files

More AppData news! I’ve been contacted by someone connected to Debian Legal, who apparently want me to add copyright information to the AppData files for licence compliance. Whilst most of the files are CC0 (basically public domain) it doesn’t seem super important, but it is technically required. If you ship an AppData file, I’d appreciate it if you could add <!-- Copyright 2013 First Lastname --> on the second line in the file. I’ve updated the AppData specification examples accordingly.

Additionally, the appdata-validate tool will warning you about missing copyright information if you use the –strict command line argument in the next release.
