During the recent Airship Working Committee meeting, the committee
addressed feedback from the Airship confirmation review [0]. One such
item was concerned with copyright footers mistakenly claiming rights to
all Airship documentation.
This change updates the footer to attribute documentation to the
Spyglass authors.
