Releave v3.32.0-beta.3 (#2187)

Improvements for all users:

• The core of the synchronization process can handle selective synchronization
  without flags (only the configuration of the selective synchronization remains
  hidden behind a flag).
• Most remote folder deletion situations should be handled and the same goes for
  remote folder exclusions as part of the selective synchronization.

Happy syncing!
