Provide configuration with fallback-values #47
Description
Everytime we add a new option to the config file, we need to adjust our config files. Even if we dont need this new option.
To improve that, we should define fallback-values for most of the options (there were it makes sense).
Current implementation:
scmcommand = generalsection['ScmCommand']
Implementation with fallback values:
scmcommand = generalsection.get('ScmCommand', "lscm")
