Relevant changelog entries:
 * show protocol in status when no ports are specified (LP: #263308)
 * update after*.rules when setting default policy (LP: #273278)
 * give useful message when trying to delete a non-existent rule (LP: #251136)
 * don't print useless newlines

Testing including developing the tests in the source, and verifying adding/deleting rules (regular and application) works properly, and that the above bugs are fixed.

The package builds, installs, and upgrades without error, and as mentioned, does not break gufw.
