An open page takes up a new version by itself after a deploy (#388)

The live stream already came back after a deploy and the lists caught
up, but the page kept running the script it had loaded, in a tab or the
home-screen app, until reloaded by hand. Back after a drop, the page now
asks for / again without the cache; another app.js named there is a new
version. With nothing to lose it reloads, and the item that was open,
carried across in sessionStorage whole since a read one is off the
Unread list, is opened again. While an episode plays, a dialog is open,
a search is set or a field is typed in, it offers a reload in a toast.

 ## [Unreleased]
 
+### Added
+
+- An open page, or the home-screen app, takes up a new version of iPX by itself once it reconnects after a deploy, back on the item you had open; while something is playing, a dialog is open or a search is typed, it offers a reload instead (#388).
+
 ### Fixed
 - Swiping, or j, through more than 50 items no longer stops at the 50th until a reload: the next ones are fetched as you near the end, and Load more on the Unread tab no longer skips as many unread items as you had read (#383).
 - On the Unread tab, a short list read through no longer asks the server for more that is not there, or shows a count of 0 items beside the items still on screen (#385).
