Add bracket position option

[Sven Lowry]

I'd like my { after method names to be on a new line, instead of the same line as the method declaration, could you consider adding an option for the extension to allow this as a choice?

I would also greatly appreciate this addition.

This does not need to be configurable; accepting the pull request to place opening bracket on newline is sufficient.

I would also really like this change. I think I'll fork this repo, add the change, and make it configurable.
