Altered for preference of versioning

Hi Aaron - I forked your repo because it had some items that I had wanted in my own script for some time that I just never got around to (such as plugins and alike).  I modified your script a little bit to work more in the way I developed and thought that maybe you might want to take a look as see if you wanted to pull some of it into your.  I basically gave the person the option to choose whether they wanted to version the whole project or just the wp-content/ directory (which is most often my choice), I don't like to use root for mysql (dev env too) so I just altered that piece a bit, and since not all my projects require mu-plugins, I'm prompting the user to select whether to add them or not.  Please feel free to hit me up with any questions, concerns, suggestions to make it better, or anything.  

Thanks for the hard work!  Awesome script!
Best,
Jason
