"Add "set -e" to postinst script to bail out on any error

Fixes lintian warning maintainer-script-ignores-errors
Move adduser from Suggests to Depends

It's used in the postinst script unconditionally, hence it's a hard
dependency.
Don't ship additional LICENSE file installed by upstream

Fixes lintian warning extra-license-file
Switch to source format "3.0 (quilt)"

Nothing really changes due that move as we don't carry any patches currently.

But this gets us some nice goodies like automatic exclusion of the
.git directory and being able to have symlinks in the debian
directory.
Move debian directory to root directory
Add permanent symlinks for init.d, default and logrotate files
Add changelog entry with non-native version

Use 0.3+dev as upstream version for now
Ignore some files when building the Debian source package

These files are in the git repo, but not included in the tar ball
build by setup.py sdist. This allows building the source package
directly from the git repository instead of just the unpacked tar
ball.
Add a debian/watch file

This declares where new upstream releases will be published and allows
Debian to recognizes new upstream releases in an automated way and
inform e.g. the package maintainer about it.

Fixes lintian warning debian-watch-file-is-missing
Use short description from GitHub as short description

It's shorter and has more information. :-)
Reindent debian/control and sort field items

Increases readability and diffability.
Done by calling "wrap-and-sort -a".
Update build.sh to work with new debian directory location
