LPS-40398 - Source format Javascript to use single quotes

Hey @mmoegelin,

Attached is an update for http://issues.liferay.com/browse/LPS-40398.  We need to make 3 updates to this:

1. We don't need to modify the scripts inside of misc/ as those are third party scripts that we don't maintain.

2. I saw on at least one of the files that there was a trailing new line at the end of the file, so go through them and make sure there isn't any (I think this was made in https://github.com/jonmak08/liferay-portal/commit/1e572a509f008cce800eb9c8feee06ba141f8c84)

3. We need to also apply this pattern to plugins.

Once that's done, go ahead and send a new pull request.  Please let me know if you have any questions.  Thanks!
