The previous commit resolved the debian build problem, but was building
packages with the stable version.  A development version is required in
the changelog to properly build development DEB packages.

Remove 1.8 debian/changelog entry with a date of "TBD" as this causes
the debian build process to fail.  We can add this back with the 1.8
release becomes a reality, or add it back now with a valid date in the
future.
