Updated README and Structure of deploy.php

I understand if these changes are totally unwelcome, but I thought I should at least try!

I updated the README mostly to be just a little more verbose and explicit.

I updated deploy.php with the goal of making configuration easier and more clear... though this is obviously going to be a matter or preference... so it was mostly just a matter of changing the way in which vars get setup, moving them to the top and making that a little more compact and easier to scan.

Additionally, I did a little more formatting of the results (which most people will not see, if they are using it correctly) ...and probably not to your liking as I just learned you are a tabs instead of spaces person... but this could be changed.
