[AppStream] AppStream 0.9.5 released!

[Matthias Klumpp]

A new release of AppStream is out.
Due to a nasty double-free corruption issue which is really hard to
track, it is recommended for all users of 0.9.4 to update soon or
backport the patch.
Aside from bugfixes, the new release also brings localized
screenshots, as requested by Endless for curated software centers.
It requires changes on software centers and metadata generators to
make full use of this new feature.

Release notes are below.
