Some bugs while setting up local environment

[kevinburke]

I was trying to get set up on a Snow Leopard Mac, and these were some of the issues I ran into - just a heads up.

• To get rake db:schema:load to run I ran into issues installing Sphinx - apparently you have to compile it separately, but Thinking Sphinx does not work with the latest stable Sphinx version (2.0.5), so you have to dig up 2.0.2 and compile that one instead.
• Bootstrapping an initial user was annoying - had to find the checks for invitation and comment them out. It may be good to create a user with a known password in the init script.
• Similarly for tags, may be good to insert at least one tag into the DB at the start so people can submit stories locally.
• rails server ran by default for me at localhost:3000, but the default configured URL is lobsters.localhost:3000, which resulted in an error after a story submission.

As far as I remember, installing Thinking Sphinx (to satisfy the gem requirement) doesn't actually require Sphinx, so unless you're running it locally, just having the gem installed should work.

I've updated the README file to show how to create the default user and tag from the console, as well as mentioning lobsters.localhost.
