Ability to specify Widdershins environment/config file

[grantlucas]

Is there a way to specify a Widdershins config file, used by --environment? There are a number of things that would be nice to specify and have passed on to Widdershins without having to have api2html support every single thing Widdershins supports.

Thanks for the suggestion! I think this would be a great addition to the api2html project, feel free to create a PR!
