[Reviewer: Tim] Fix secure connection support

Tim,

Please can you review my fix to secure connections?  The `dh_installinit -pclearwater-secure-connections` line was missing from `debian/rules` - I think you added this block but this package was missing from the list.

(Note that this pull request also includes the automatic upgrade package - I'm expecting that you'll review that first, at which point this diff will disappear.  git would have complained about the diff if this merge didn't include it.)
