Select Entity type in UI for imports

[sleidig]

Importing data I want select the entity type of the data in the user interface, so that I do not have to add type or uuid in my uploaded file manually.

Additional Info

• The available entities that could be displayed as dropdown can be found in the ENTITY_MAP (

  ndb-core/src/app/core/entity-components/entity-details/entity-details.component.ts

  Line 27 in c889c40

  export const ENTITY_MAP: Map<string, EntityConstructor<Entity>> = new Map<

  )
• uuid for a new entity can be created automatically by the class constructor of Entity
