Tutorial.rst: Change documentation about .coafile
Tutorial.rst: Change documentation about .coafile

Replaced the deprecated [Default] section by [cli].
Assigned True to use_spaces instead of yeah.
These changes were made because the previous documentation was
inconsistent with the observation upon execution of coala.

Closes https://github.com/coala/coala/issues/4968
