* I need to stop rewriting builtin methods with reduce.
* Removed redundant fields from the config class.
* Added a warning when module version and beau.yml version differ.
This is mostly some clean up. Now plugins are checked for existence
before being required. The regex for dynamic values was improved a
little in an attemp to make it more reliable. Plugins are only required
once now.
The CLI's CWD is set to that of the config file. This makes relative
paths mentioned in the file more reliable.
This introduces a top level key: `hosts`. It's an array where you can
configure multiple hosts with their own requests, they share defaults
and environment with the global scope.
This allows you to have multiple paths being the same with different
endpoints and settings.
