Cozy Drive folder & Windows automatic updates

This is for testing purpose only.
Do not install it, unless you know what you're doing.

Improvements for all platforms:

• Files are now synchronized to your Cozy Drive folder (to better match the
  Cozy Drive app name). If your already had a Cozy folder set up,
  Cozy Desktop will continue to use it. If you want to switch to the new
  folder, you can disconnect from your Cozy in the Settings, rename your local
  Cozy folder to Cozy Drive (so you don't need to download everything
  again), then restart Cozy Desktop, register and use the new folder.
• Your computer now appears in your Cozy as Cozy Drive (your computer name).

Improvements for Windows users:

• Installer and app are signed now, which should prevent warnings and allow
  us to support automatic updates. Since we use a standard certificate (not
  one with Extended Validation), you'll still get a confirmation popup at
  install time, until the app gets enough reputation in Microsoft SmartScreen
  (the anti-phishing system included in Windows 8 and later).
• This release (and upcoming ones) should now support automatic updates. But
  previous releases didn't, so you'll still have to download and install this
  one by hand.
• A third-party component used by Cozy Desktop to monitor your local folder
  was updated, fixing some issues on Windows.

Happy syncing!
