#8000: Fix rename issues in dashboard
- Do not display the full path of the selected item in the text box (**warning** : this removes the possibility of moving a file/folder using the rename dialog. Maybe someone finds this helpful)
- Adapt dialog for files and notebook.
- Do not allow renaming a running notebook (currently, renaming a running notebook would result in duplication instead of renaming after the open notebook saves/autosaves using the old name)
