Code smell: Two space indentation

Replaced 106806 occurances of ^( +)(.*$) with

The ruby community almost universally (i.e. everyone but Luke, Markus, and the other eleven people
who learned ruby in the 1900s) uses two-space indentation.

3 Examples:

    The code:
        end

        # Tell getopt which arguments are valid
        def test_get_getopt_args
            element = Setting.new :name => "foo", :desc => "anything", :settings => Puppet::Util::Settings.new
            assert_equal([["--foo", GetoptLong::REQUIRED_ARGUMENT]], element.getopt_args, "Did not produce appropriate getopt args")

    becomes:
        end

        # Tell getopt which arguments are valid
        def test_get_getopt_args
          element = Setting.new :name => "foo", :desc => "anything", :settings => Puppet::Util::Settings.new
          assert_equal([["--foo", GetoptLong::REQUIRED_ARGUMENT]], element.getopt_args, "Did not produce appropriate getopt args")

    The code:
            assert_equal(str, val)

            assert_instance_of(Float, result)

        end

        # Now test it with a passed object
    becomes:
          assert_equal(str, val)

          assert_instance_of(Float, result)

        end

        # Now test it with a passed object
    The code:
        end

        assert_nothing_raised do
            klass[:Yay] = "boo"
            klass["Cool"] = :yayness
        end

    becomes:

        assert_nothing_raised do
          klass[:Yay] = "boo"
          klass["Cool"] = :yayness
