Temporary is temporary

Improvements for all users:

• We added a new icon set for the Offline status. Prior to this version,
  whenever we detected you might be disconnected from the Internet, we would
  display a "pause" icon with the "Disconnected" status label. We're now
  displaying a shadowed version of the main icon and a "No Internet connection"
  status label. We hope this is clearer to you.
• We fixed a bug in the way we sort changes coming from your remote Cozy. For
  some changes like the replacement of a file, the order in which we receive
  changes from the remote Cozy is crucial to applying it correctly on the local
  filesystem. In this particular case, we were not always sorting correctly the
  deletion and recreation of the file (or folder) which could lead to documents
  disappearing or conflicts to appear.
• We are now able to detect the use of a temporary file in some situations and
  correctly handle it (i.e. not move it to the trash and synchronise the new
  version).
• We've updated again some of our dependencies that don't require changes in
  our code. Those are the same that were upgraded in v3.13.1-alpha.1
  then downgraded back in v3.13.1-beta.1.
  We investigated, identified and excluded the problematic updates, so
  networking should work as expected this time.

Improvements for Windows & GNU/Linux users:

• When renaming folders and deleting part of their content while the client
  was stopped, the deletion should now be properly handled on restart.

Improvements for GNU/Linux users:

• We've mitigated an issue LibreOffice users could encounter while saving.
  LibreOffice uses an intermediary temporary file when saving and in some
  situations we could end up deleting the file altogether or move the previous
  version to the Cozy's trash and even not be able to synchronise the new
  version.
  We're now ignoring those temporary files (i.e. with extension .osl-tmp)
  which results in a correct update of the office document.

Improvements for contributors:

• We've decided to run prettier over our entire codebase with the cozy-app
  eslint config and to keep using it from now on. This will remove the need to
  check for syntax errors and improve homogeneity between Cozy Cloud javascript
  projects.

Changes that should have no effects:

• We did some minimal refactoring on our proxy setup to introduce some tests.
  There should be no effects on the way the proxy works.

There are some known issues that we'll tackle in the next releases:

• When we don't detect any update closely following the temporary file deletion
  and that file is not ignored, we end up deleting the file that was saved.
  This is a more general situation and should be fixed very soon.
