The list of components (and most of this file's content) is used by the OpenVisualizer to display e.g. error messages. The ```GenStackDefines.py``` script [1] parses ```openwsn.h``` to create ```StackDefines.py```. After merging this PR, I'll run the script and commit the revised ```StackDefines.py``` in the openwsn-sw repo.
