Feature/install script generator

This MR introduces a python script that generates an install script for a selected module, together with python functionality to get the dependencies of a module and the currenlty used versions, as well as automatic patch creation for unpublished commits and uncommitted changes.

These functionalities were originally contained in getusedversions.sh and extractmodulepart.sh. The first should not be needed anymore, while the latter has been reduced to not generate an install script anymore.

The generator script expects the module (for which an installation script is to be generated) to already be a git repository with a defined remote origin.
