Create world

[daniel-deboeverie-lemon]

This merge builds on from https://github.com/olexale/bdd_widget_test/pull/60 since it needed a few changes made there.

This PR adds/fixes the following;

• A addWorld flag to the generator options
• When this flag is true it adds a World object to the generated feature files, step files and hook files
• The World contains a parameters prop that is a key value map that can be edited by the developer.
• Since the hook file is now dynamic, changed it to use the constant declared method names
• Fixed an indent issue for if only hooks were enabled (without an after in the feature files)
• Fixed a formatting issue for the beforeEach hook

I'm not familiar with the notion of world in BDD. Do you have any documentation about it?

As discussed in #62, this might be achieved with good old DI, so I'm closing the PR. @daniel-deboeverie-lemon, thanks once again for your work!

If you believe it would still be beneficial to introduce the World, feel free to reopen the PR, and let's discuss.
