[PATCH] Make rails console load ~/.railsrc and RAILS_ROOT/.railsrc

Here's tiny patch that makes rails console load ~/.railsrc and RAILS_ROOT/.railsrc.

I find it useful to define general and project specific utility methods for use on the console.

For instance, I have a (probably far from perfect) method editing an object as YAML in a text editor (KDE kate, in this case):

def edit(obj)
  ar = obj.kind_of?(ActiveRecord::Base)
  Tempfile.open('edit-object') do |f|
    yaml = ar ? obj.attributes.to_yaml : obj.to_yaml
    f.puts(yaml)
    f.close;
    system "kate '#{f.path}' 2> /dev/null"
    f.open
    changed = YAML.load_file(f.path)
    if ar
      obj.attributes = changed
      nil
    elsif obj.respond_to?(:replace)
      obj.replace(changed)
      nil
    else
      changed
    end
  end
end
