Eventscripts: Untested factorisations and introduction of status event.

This is the first stage of an experimental change to eventscripts.
Ronnie and I did a few hours of factorisation of 40.vsftpd and applied
many of the changes to 41.httpd.  Other eventscripts were also
modified.

At this stage this is completely untested.
