The previous setting didn't complain if uscan didn't find a signature
which doesn't help security wise. It would still allow an attacker
to modify the source package. This change now requires a valid
signature for the source package.
This change switches the package version number for packages that
are intended for the Debian package repo to match the Debian policies.
It also removes the comment from the watch file.
This change fixes the launchpad build script and also improves
updating the watch file.
If we use the variables that uscan provides we don't have to
hard-code the package name in the watch file. This makes it possible
to use a generic one for all packages.
