Generate an information file

[mallorydxw]

We want the commit hash of the deployment to be available as a constant (so that dxw-extras can display it on the dashboard).

So we should generate a PHP file that contains something along the lines of the following:

<?php
define('WHIPPET_DEPLOY', true); # this repo was deployed with whippet deploy
define('WHIPPET_COMMIT', 'def'); # the commit hash used in this deployment

If we think of any more useful information, we can add it later.

(WP should load this file. If we can't figure out an easy way to do that, we can add a require() line to chef's wp-config.php).

We keep saying we want this but I'm not totally sure why.
