Fix for having no config file

[stangelandcl]

This is for running without a config file. This change checks for a Settings section, which won't exist because the config file does not exist, otherwise exceptions are thrown and the script will not run.

@stangelandcl Is the idea for this set of changes to for the script to run with just default settings?

[stangelandcl]

Yes. I just set the defaults to what I want and run the script without any config files existing.
