Improve error message when no `di.yml` is found, or `di.yml` is empty #8

Currently, when running without a di.yml file, one gets the following error. Since this will be a common thing, the output should probably be a bit more user-friendly.

$> di build                                                                                                               ⏎

FileNotFoundError: missing configuration; could not find configuration file 'di.yml'

Equally, when the di.yml is empty, the output currently is:

$> di build                                                                                                                 ⏎
