"Debianizing" ser2sock

Hello,

I have added files to automatically build a .deb packaqge under debian/ubuntu (using debuild).
These files are under the debian/ directory.
There are also minor modifications inside the original files to comply with the Debian policy of packaging.
I thought I might share this for inclusion in the main source tree, as installation is much cleaner using a .deb package built from sources (at least under Debian or Ubuntu).

Regards,
