JavaScript object :js:`top.fsMod` managing the "state" for page-tree and
file-tree related contexts in the backend user-interface like this:

* `top.fsMod.recentIds.web` contained the current ("recent")
  page or file related identifier details were shown for
* `top.fsMod.navFrameHighlightedID.web` contained the currently
  selected identifier that was highlighted in page-tree or file-tree
* `top.fsMod.currentBank` contained the current mount point or
  file mount ("bank") used in page-tree or file-tree

To get rid of inline JavaScript and reduce usage of JavaScript `top.*`,
mentioned `top.fsMod` has been deprecated and replaced by new component
`ModuleStateStorage`. Reading data from `top.fsMod` is still possible
as a fall-back.
