Wrapper method that is called by the Bolt executable. Parses the command and then loads the project and config. Once config is loaded, it completes the setup process by configuring Bolt and logging messages.

This separation is needed since the Bolt::Outputter class that normally handles printing errors relies on config being loaded. All setup that happens before config is loaded will have errors printed directly to stdout, while all errors raised after config is loaded are handled by the outputter.
