Include date files in the Debian package
"environments", "public" and "views" are now available in the Debian package. The instance started by the provided systemd.service file will find them thanks to the DANCER_APPDIR environment variable.
This solution was chosen such that during development, it is still possible to follow the Dancer introduction and tutorial as well as use plackup or any of the ./bin/* files directly as usual.
A CI job is added to check that the login page appear to be served when the application is started in a similar way it would be started when systemd is used (systemd is unfortunately not easily available on GitLab CI).
Closes #16 (closed).
