Title: Newsletter tweaks

I am locally using some modifications to the Contao newsletter module. Maybe some of them are useful for merging into Contao master. All the individual patches can be applied separately and they do the following:
* use the current backend user to determine sender name and mail address
* show plain text newsletters in monospace font
* hide the separator when only one of HTML or plain text is present
