Renaming a collapsed function UX

[AdRiley]

Renaming a collapsed function needs to be:

1. From outside the function:

• a menu item on the extended component menu

• Clicking this button makes the name of the selected collapsed component editable.
• Pressing enter or clicking off commits the rename

2. When components are grouped they should automatically enter rename mode allowing a user to type a new group name

Refinement notes:

• extend API of widget context allowing registering actions by widgets
  • For the future: the right click on a widget could display a context menu narrowed to actions of this widget (and its ancestors) only.

Refinement notes:

• The name should be editable only in "main function calls", i.e. when we can enter the function.
• To display WidgetFunctionName immediately after collapse, let's provide ourselves the method call we expect.
• Split the auto-rename to a separate task. (estimates 2/3)
