* Neither support for all further packages used at KARA nor any used for
the Jena-project

* LaTeX rule still seems not to be that stable, therefore removed from
site.yml
* Rename all versions to lasarchiv1 to be consistent
* Update SSH playbook of common rule to open the ports in the firewall

* Depends on lasarchiv1 rule which is currently not implemented in a
laptop save way

* Mostly Python 3
* Many packages are (nearly) up-to-date in Fedora 25 in comparisson with
* ipynb role for IPython notebooks
* pyhon_stack for the common scipy-stack

pip, so I use these packages.
