Synchronizing preparations in similar plans

If you use similar plans in several different courses (e.g. when teaching parallel courses with copied plans), a "Synchronize with similar plans" button appears when creating preparations in one of them. The synchronization is based on identical title of topic in different teaching plans.

Preparations synchronize by confirming the synchronization. The same preparations will be attached to topics in similar plans. No need to attach the preparations to each plan manually.
