[AppStream] AppStream 0.12.1 released!

[Matthias Klumpp]

Hello!

This new release of AppStream brings a lot of new features, most
notably the addition of the "repository" component type to write
metadata for software repository additions[1] as well as a new
"agreement" tag to add EULAs and GDPR privacy statements to new
software installations. The agreement tag goes especially well with
the "repository" component type to make adding new 3rd-party software
repositories opt-in and GDPR compliant.

Additionally to those changes, a lot of other new features have been
added and a few bugs were fixed. Refer to the full changelog below.
