    Config: add method dump_config
    
    This patch adds a method that returns the currently loaded config values
    in a .ini file formatted string. In the future it will be used to create
    the config file in users home directory.
    
    I decided to dump all config values and use the '=' operator. Using the
    '+=' where it can be used would make more sense but it would be more
    complicated to implement and I currently don't see any pretty way to do
    it. But I might change this in the future.
