To make indentation work with less effort. The modeline was copied from
libostree with minor modification and the .editorconfig from GLib.
The advantage of having both a modeline and an editorconfig is we can
work out of the box on more editor setups, and the modeline allows us to
specify the style with a lot more fine grained control.
We only interested in a few of the attributes of some
tags, but we shouldn't fail if other valid attributes
are present.
Add some of the allowed attributes to the <release> element
in the appdata test and verify that we can still parse it.
The appstream spec is here:

Approved by: matthiasclasen
The spec allowed either timestamp or date to
be specified for a release, so we should support
both.
