Renaming appdata and desktop file for GCompris

[Harald Sitter]

Hi,

Do note that the appstream file name  and the desktop file name do not
need to be the same. An appstream file tags a specific desktop file as
<provides> [1]. So technically you do not need to rename it, you only
need to change the desktop file and the provides entry. If you want to
rename it do note that the <provides> tag may contain an <id> tag,
that's where you specify your old name and the appstream tooling will
know that your component has two names.

Lastly, I *think* you do not technically need to rename anything. If
you want you should also be able to use KAboutData::setDesktopFileName
[2] respectively QGuiApplication::setDesktopFileName [3] to help the
task manager resolve the desktop file from your process without having
to rename anything.
