$SubjectName variable unused; clean up
$SubjectName variable unused; clean up

Having used this script several times today, I came to notice the $SubjectName variable, being passed in via the CLI, is essentially ignored when generating the SSL certificates, rendering it useless. I believe it's a good idea to have it in place, so I've updated the script to reflect this.

I also cleaned up some random new lines throughout the file, and expanded on a comment.

It might be worth going a step further and commenting the file fully, as most people reviewing this file won't be familiar with PowerShell (like I wasn't unitl a few days ago). It could be helpful.
