tdf#126700 allow replacing the default documents

Per default, a document opened by a user action will always open
in a new frame. For tdf#83722, this behaviour was extended to
documents created from templates.

But this currently also affects the default factory templates, if
these are replaced by a config setting with a real template, which
was not intentional.

So this patch introduces a new MediaDescriptor property, which
allows to mark a document as replaceable and automatically sets
it for factory default documents. If this property is set to true,
a document just acts as a placeholder while it's unmodified. I.e.
the next opened document from its frame will close and replace it.
