v0.52

Sabine 0.52

• Fix Sabine apps failing to open on Linux with "The application could not continue" after the
  computer's hostname changed, as it does on laptops that take their name from the network, or
  after a crash or power loss. Chromium found the lock its last run left in the app's profile,
  took it for another computer using that profile and tried to ask in a dialog the desktop can't
  show. Sabine now clears a lock no running Sabine browser holds before Chromium starts, and a
  shared Chromium no longer takes an app's profile while the app's own Chromium still runs after a
  hostname change.
