This adds a new Expansion menu button to the Hierarchy View that provides the ability to store the current Visible Set ( scene expansion, inclusions & exclusions ) as a named bookmark that is saved with the script. This makes it fairly straightforward to bookmark one or more common states for quick access.

As these bookmarks are saved with the script, there is some cost in increased file size when bookmarking large expansions. For example, a bookmark expanding ~43,000 locations in the ALab results in an additional 860KB of data saved in the Gaffer script. Comparing this to bookmarking the same ~43,000 location expansion using an equivalent feature in a leading commercial DCC results in an ~11MB increase in their scene file, so we're not doing terribly by comparison... and if you were to instead bookmark an inclusion of the root of the ALab, that would only be a 1.3KB increase in the Gaffer script.
I've structured this a more generic Expansion menu with a Bookmarks submenu in case we want to add other expansion related actions here in the future ( collapse all, clear inclusions, etc ), though happy to refine if anyone has better ideas.
