Addition of willow:docs and when willow launches as a project

• willow willow:docs will launch the Willow User's Guide in the default web browser
• When Willow is launched as project it will suggest running ./willow willow:docs
• Ejecting has a small theatrical change -- Willow text art exit stage right.

CORS handling and fix to Eject task

CORS handling was made optional via .env:

• set CORS=true if you want Willow to handle CORS.

The willow:eject task was not properly updating the controller/route registration in Main/App.php:

• The base namespace was remaining as 'Willow' instead of being replaced by the project name
• This was solved when the v1 group routes are registered by using self::class to determine the base namespace.
