Some build and package improvements (#45)

* add missing package version to change log

* fix some warnings of lintian during deb build

* simplification of the debian package

* introduce build script with docker/podman support

* use already existing ssh proxy, has the nice effect of not displaying the welcome message

* update readme for 1.0.2

* fix missing argument in apt-get autoremove

-* The new package is exactly the old steps packaged in a debian package
-* [dpkg-build-files](dpkg-build-files) contains the scripts that build the package (using dh_make and debuild) if you want to build it yourself / change it
+* [build_deb.sh](build_deb.sh) can be used to build the package by yourself.
+    * [dpkg-build-files](dpkg-build-files) contains the sources that debuild uses to build the package if you want to build it yourself / change it
+    * by default it uses docker or podman to build the debian package
+    * use ```./build_deb.sh build``` to not using a container
+    * the resulting package will be in [packages/](packages/)

 * Built on Ubuntu-20.04 on Windows 10/WSL2
