To beat ticket #5525, we must have a method for archiving a layout
hierarchy alongside a BView hierarchy. To do this, both BLayout and
BLayoutItem must inherit from BArchivable. In addition to this, I've added
two new methods to BLayout: ArchiveLayoutData() and RestoreItemAndData(),
the first is called during archiving to allow a BLayout to add any extra
data for an item into its archive (the data stored in
BLayoutItem::fLayoutData, for instance). BLayout::RestoreItemAndData() is
called in BLayoutItem::AllUnarchived(), and implementations of this method
will add the item in question to the layout, using the data that was
stored in ArchiveLayoutData().
