Ruby 1.9.2 Load paths

Wrong way to deal with the 1.9.2 removal of . from the loadpath:

1. require "./foo/bar" forces you to run code from your project root
2. $LOAD_PATH.unshift(".") recreates security issue, and pollutes

Right way to deal with the 1.9.2 removal of . from the loadpath:

1. require_relative "foo/bar" if you don't need Ruby 1.8 compatibility
2. require "#{File.dirname(__FILE__)}/foo/bar" if Ruby 1.8 compatibility needed

Requiring a file somewhere else in the project relative to this file: require File.expand_path('../path/to/file', File.dirname(__FILE__))
