Site update

Recovered old versions of the Scattered roster, Birch family tree, and Sweetleaf family tree files, and have activated links to them on the See Also page; fixed broken footers on all the subpages and made the footer on the main page match the overall site footer. A telling of the tale of Birch and the Scattering has also been added. Status of Natil as resuming OOC chieftain has been noted on the appropriate pages.
