Bug#846463: Depends on default-jre-headless and Suggests default-jre?

[殷啟聰]

Package: proguard
Version: 5.3.1-1
Severity: wishlist

proguard is mostly used as a command line program and used by various
build systems such as the Gradle Android Plugin. There's no need to
force install the headful JRE together with Proguard. Perhaps putting
it to Suggests is a better approach?
