Fixed bad carriage returns

Ubuntu Rails stack

#!/bin/bash
# Inspired by http://blog.fiveruns.com/2008/9/24/rails-automation-at-slicehost
#
# This is a fork of: http://gist.github.com/16225
#
# To it I've added:
#  - Installation of the MySQL gem which is no longer included with Rails
#  - A switch from Passenger 2.0.3 (specified in the original script) to 2.0.6
#  - Explanatory text at the end of the script to help the user understand
#    what to do next.
