- Enable automatic layouter only for diagrams without rounded edges, which is the case if none of the positions of the connected connectors is specified using an angle (i.e., in particular also if the model does not contain any connectors, or none of the connectors is connected to a connection).
- getContributedItems(): Use shortcut style when checking conditions, i.e. return dedicated value at as soon as possible, instead of using nested ifs

  - Do not use Eclipse Job. Action is already in a separate thread, and 'Job' is much slower
  - Disabled annotation view update when applying layout update
