Global Reading of workspace.ini
Functions for reading the workspace.ini files in /etc/vispa/workspace.ini and $HOME/.vispa/workspace.ini have to globally available. Furthermore there must be a merge between the content of those two files. Currently this is only available in the examples extension. The implementation should be done in vispa/remote/filesystem.py and in vispa/controller/filesystem.py.
