`image/x-icon`.

* Remove wrapping div with inline styles for hidden form fields.
We are dropping HTML 4.01 and XHTML strict compliance since input tags directly
inside a form are valid HTML5, and the absense of inline styles help in validating
for Content Security Policy.
*Joost Baaij*
* `collection_check_boxes` respects `:index` option for the hidden filed name.

*Vasiliy Ermolovich*
* `date_select` helper with option `with_css_classes: true` does not overwrite other classes.
*Izumi Wong-Horiuchi*
* `number_to_percentage` does not crash with `Float::NAN` or `Float::INFINITY`
as input.

*Yves Senn*
* Add `include_hidden` option to `collection_check_boxes` helper.
*Vasiliy Ermolovich*
* Fixed a problem where the default options for the `button_tag` helper is not
applied correctly.
Fixes #14254.
*Sergey Prikhodko*
* Take variants into account when calculating template digests in ActionView::Digestor.
The arguments to ActionView::Digestor#digest are now being passed as a hash
to support variants and allow more flexibility in the future. The support for
regular (required) arguments is deprecated and will be removed in Rails 5.0 or later.
