reconfigure pure-ftpd

the updater asks this:

Reconfigure Services? (yes,no,selected) [yes]
Reconfigure Pureftpd (y,n) [y]

Pure-ftpd should be configured for new installations and reconfigured for updates, when the user wants to reconfigure Pure-ftpd, and not reconfigured when the user doesn't want.

I have tested this in a productive server, and Pure-ftpd wasn't fully reconfigured, when I pressed y for reconfiguring it.
