flatpak: set appdata release version for dev version: appdata file can now use a template (which has the same name with "_tpl_" prefix), which is used in dev version to automatically set the release with the right Mercurial revision/date. Comment from org.salutatoi.Cagou.appdata.xml has been moved as first child of <component>, so it is not lost while parsing the file.
