nemo 0.15.4

Changed

• Opening the web app again is faster, most on a slow connection: each
  version of the app is now kept by the browser for good, so only the
  page itself is checked for a newer one, rather than every file one
  after another. On a slow mobile connection a repeat visit went from
  about 1.6 seconds to 0.5.
• The nemo logo inside the app is now the mark on its own, as the web
  app's loading screen shows it, rather than the mark on a rounded tile.
  On the web the loading screen now hands over to the app without the
  logo jumping. The app's icon is unchanged.
