Add a newline to end of file for each file that doesn't have one.

[eflynn]

Changes proposed in this Pull Request:

Inserts final newline to files that need it. stylelint barks at you if you don't have a newline at the end of a file. Also it's easier to read files on the shell with cat, for example. An .editorconfig file would enforce this, but it was debated before that it was a matter of personal choice since this is a template for WordPress themes and not an actual theme.

Thank you @eflynn for the PR. It seems this PR is doing the same thing as #1153.

[eflynn]

Ah, thanks, I didn't see that one. Funny I tried to search for something like it and didn't find that one. Can you merge this or the other one? #1153 was posted 9 days ago...

Yes, it seems like GitHub does not handle fuzzy search well.

As I have now mentioned in the other PR. I would like to see the new line being checked for in travis before the changes are made so that they do not get reversed by mistake in the future.

Git diff already warns you about this issue. I think you can add a pre-commit hook for git that would block a commit based on this issue? I'm not sure.

However, I strongly vote for the .editorconfig solution, because it solves the problem at the editor layer and is well supported. There is already a config for Wordpress itself:

I think it may be best to close this PR and keep the discussion to #1153 instead of two places. We can always reopen the PR if need be-

Closing this out in favor of #1153.
