FXML refactoring

[ghost]

As agreed with @chimp1984 in this thread we need to refactor places where FXML items are added (early dev state left-overs) and use imperative approach in java classes.

Checklist:

• specify all affected views
• (OPTIONAL) measure performance of fxml loading
• do refactoring
