[issue2551179] Load config_ini.ini and properly recognize minimal template for roundup-demo.

New submission from John Rouillard:

See: https://github.com/roundup-tracker/roundup/pull/2 for jerrykan's solution.

I committed the config_ini.ini load as is.

For minimal, I used the basename of the directory path to the template rather
than including a field that isn't required in the minimal template.
