It needs some improvement. With hard work I got working newsletter 
system. My customer wanted CSV-import also.

* da_newsletter_subscription - needs some new fields and TCA in order to 
work with wil_importcsv

* wil_importcsv - with TCA for da_newsletter_subscription and a some 
modidications imports users

* tcdmail2danewsletter - use users stored by da_newsletter_subscription 
in order to send newsletter using tcdirectmail - no changes needed

* tcdirectmail - send mail and can directly use data of 
da_newsletter_subscription - no changes needed

Note.  	da_newsletter_extended - that might cause duplicate users - 
don't install, if the author doesn't have fixed version of this plugin.
