- Add separate permission for showing the action. This makes it
easier to restrict usage of Search and Replace if wanted. By
default the same roles have this permission as for the standard
'Modify portal content' permission. Added upgrade steps for this.
Permission title is: 'collective.searchandreplace: Use Search And
Replace'.
