A New WordPress Script

I've been working on some scripts to help with the deployment of sites to Apache lately. My original script was pretty simple.
I used it to automate the creation of vhost entries when I added a new site to the server. Since one of my clients actually uses WordPress
for all it's sites, and we have been working to migrate all the sites from a multi-site installation to stand alone sites, I needed
an easy way to setup a Wordpress site on the new server. Ideally I wanted to be able to pass a script the site name and it create the
folder in var/ , install the latest copy of WordPress, install the base themes and base plugins and setup the proper vhost entry
in etc/

Ultimately I'd like to be able to incorporate this into a website so that we can install a brand new standard base install of WordPress with
the press of a button. (I don't like how gists are embedded in jekyll so I am usinga code block + including the link to the gist)

My standard disclaimers apply here. If you do not know python well enough to follow the code, I am not liable for any issues that
might come up trying to use this code. If you know python better then me (not a huge strectch!) please leave any comments below on
your opinions on how to make this better!! Also, I am happy to help anyone out who wants to use this for something and need assistance.
My python is not by any means stellar, but I can get most things done with it!
