Contact Management e-mailing and export to Excel

The new BCC feature in Contact Management enables the sender of an e-mailing to receive a blind carbon copy of his e-mail in his own mailbox. It will work with or without the option "API for bulk mail" checked. 

On top of this we added the new action "Export to Excel" with which you can export the selected contacts to an Excel file. The column headers are consistent with the column headers in the template for the user import functionality. The export file includes the unique user record id so you can use it to make corrections in Excel, save as "CSV" and reimport the corrected list back into your portal.
