Ignores .rubycritic.yml file

I tried testing with the example .rubycritic.yml configuration file:

mode_ci:
  enabled: true # default is false
  branch: 'production' # default is master
branch: 'production' # default is master
path: '/tmp/mycustompath' # Set path where report will be saved (tmp/rubycritic by default)
threshhold_score: 10 # default is 0
deduplicate_symlinks: true # default is false
suppress_ratings: true # default is false
no_browser: true # default is false
format: console # Available values are: html, json, console, lint. Default value is html.
minimum_score: 95 # default is 0
paths: # Files to analyse.
  - 'app/controllers/'
  - 'app/models/'

Changes in the configuration file (e.g., no_browser, path, and paths), don't affect the settings rubycritic actually uses when it runs. It appears to always use the default settings (i.e., as if the .rubycritic.yml wasn't present) unless command line arguments are specified (then the CLI setting is used). When rubycritic runs, it does read the configuration file. It just appears to ignore the settings.

Also, it looks like the documented format option for the config file has changed to formats but the documentation hasn't been updated to match (see RubyCritic::Cli::Options::File::formats).

Start by tracing how .rubycritic.yml is read and how RubyCritic::Cli::Options::File::formats is used. Reproduce the example configuration, checking why options such as no_browser, path, paths, and format do not affect execution; done means the file settings are honored and the documented format option matches the supported name.
