Setup help

I made some modifications and added some documentation to make it easier for anyone to run this themselves. It's still not great, it assumes you know how to install and run apache/php/mysql, but I have a local copy running with this :)

Also note that I put in sample values for the database host, username and password in the config file, so if you merge this, you'll need to modify those to put back your values like anyone setting this up would.

I was a little concerned when I initially saw your DB credentials in the repo, but I tried to connect to it and it looks like you have that account locked down to only have access from your web server, so that's good :)
