Testing Scenarios 2.2

More parallelism for file transfers

If you sync a lot of small files, it should be faster than with 2.1.2.

Syncing with outdated server

If you sync with a server 6, you should get a red warning and the sync folder should get paused.

Test with new Credential store on Windows

When upgrading from a working 2.1.x installation on Windows to 2.2, the client should not ask for a password.
