Docks used by editors are broken in embed enviroments

Any editor depending on the need of Docks needs a Perspective around it to have the Docks included.

This means the Appformer standalone editor perspective or any custom perspective that uses these screens does not show the Docks panel and the editor lacks editing features.

Areas hit by this issue:

• DMN Editor
• Data Modeller
• Scenario Simulation editor
• Case management editor
• BPMN Process editor
• Page authoring editor
• Form layout editor
• Manage section

Possible fixes:

• Add a dock for the editor
• Add a dock for appformer standalone perspective

Might be it is enough to add the dock for standalone perspective. This needs some investigation.
