System now exports a content package and imports one, by upload or from
var/pakete. Pages with their revisions, areas, menus, media, forms,
redirects, terms, translations, design and settings are replaced;
submissions, statistics, tasks, plugin state and service keys stay, and
accounts only come along when that is chosen explicitly. A backup comes
first, the site is in maintenance meanwhile, and every file and document
in the package is checked before anything is written.
