Replace contrib/debian/ with a note on how to install on Debian.

Since gitflow is packaged for Debian and is available for testing and
sid already, remove the contrib/ directory in favour of using the
official Debian package.

Also mention how to install gitflow on Debian in the README.mdown.

Furthermore, Debian-specific things were removed from Changes.mdown
and the Makefile.

+#### Debian
+
+Users of Debian testing and unstable can use the apt-get tool to
+install gitflow from the Debian repository:
+
+    $ apt-get install git-flow
+
+For Debian stable, one can either use the git flow installer, or the
+Debian package from unstable (it works just fine on stable too).
