Proposal: Configuration Option to Convert Component Name to Kebab Case

[mlturner88]

As the official Vue Style Guide recommends using pascal case naming for components, I would like to propose adding a configuration option to convert the component's name into kebab case for the CSS block class name. I know that right now it is possible to add a block attribute onto the component with another name to override what the component is named but this means re-writing every component name in kebab case manually to adhere to the style guide and BEM naming conventions.

I would be willing to work on a PR for this if you want. If so, please let me know and if you have any guidance or preferences on how that should be accomplished. Thanks.
