Description
There isn't any documentation for config yet. We need a central page explaining how ENV, CLI and file configuration come together. In which order they're processed and for which circumstances you'd use either of them.
For documenting other methods (e.g. Actions/setHttpAuth) we could then link to this documentation and cut down on individual examples substantially.
We might want to simplify the API itself as well, go from test.config.get('USER') to test.config.user or something like that.
A suite could provide suite-scoped overwrites for config values in its options property. In the Q-Project, we might use this to run tests against local and remote environments without duplicating too much of the suite setup.
