wp scaffold and WPCS

[sandrodz]

Files generated by wp scaffold command are not WordPress coding standard compliant!

For example cpt generated:

wp-cli/wp-cli#4589

Close via #110

Oops, maybe the other files apart from CPT aren't compliant?

Edit: no there're not - taxonomy for one.

Edit2: Taxonomy fixed now via #112, need to check if there's others...

@schlessera, @danielbachhuber - is there any Behat logic that would run linters on generated files? That would be great to ensure we scaffold files that are WordPress compliant.
