sw content controls, dropdown: add an initial properties dialog

- read the doc model: show if a content control is a placeholder or not

- work with a shared pointer in the dialog, which avoids lifetime issues
  in case the content control we edit in one view gets deleted in an
  other view

- write the doc model: set the placeholder mode of the content control
  based on the checkbox state and mark the doc as modified if any widget
  is touched when pressing OK

- handle command state: allow this dialog only inside content controls
