Revert "Remove `:disable_with` in favor of `'data-disable-with'` option from `submit_tag`, `button_tag` and `button_to` helpers."

`disable_with:` is much easier to type than `"data-disable-with" =>`,
and the fact it uses "data-disable-with" => is an implementation concern,
it should not affect the public API.

This reverts commit 683fc4db.

Remove `:disable_with` in favor of `'data-disable-with'` option from `submit_tag`, `button_tag` and `button_to` helpers.

the select method (tag select) forces :include_blank  if is required and no multiple and
display size is one

This replaces `include_seconds` argument with an option key
`include_seconds => true` in options hash.

Also `time_ago_in_words` now passes options hash, including a `locale`
key, which makes in compatible with `distance_of_time_in_words`.

Fix failing test: Mime::JS generates "text/javascript"

closes #3341

This may break existing tests that are asserting the whole session contents
but should not break existing tests that are asserting individual keys - e.g:

class SomeControllerTest < ActionController::TestCase
  setup do
    session['user_id'] = 1
  end

  test "some test" do
    get :some_action, nil, { 'another_var' => 2 }

    # This assertion will now fail
    assert_equal({ 'another_var' => 2 }, session)

    # This assertion will still pass
    assert_equal 2, session['another_var]
  end
end

Fixes #1529.

The release date details have been taken from
http://weblog.rubyonrails.org/2012/3/30/ann-rails-3-2-3-has-been-released/

Add index method to FormBuilder. Useful when you use field_for and need to know the index number into the iteration.

Changed default value for `config.action_view.embed_authenticity_token_in_remote_forms`
to `false`. This change breaks remote forms that need to work also without javascript,
so if you need such behavior, you can either set it to `true` or explicitly pass
`:authenticity_token => true` in form options

There is a regression introduced in 16ee611f, which breaks
remote forms that should also work without javascript. This commit
introduces config option that allows to configure this behavior
defaulting to the old behavior (ie. include authenticity token
in remote forms by default)

Conflicts:

	actionpack/CHANGELOG.md

Do not include the authenticity token in forms where remote: true as ajax forms use the meta-tag value

Also add missing entries and use the formating convention

Last commit message should not have said 'Rails 4' either

This was implemented in 2ee4dd85

Set "March 1, 2012" as the release date for 3.2.2, 3.1.4, 3.0.12
