When submitting a <form>, browsers will serialize the element that
initiated the submission as part of the FormData, including itsname and value attributes.
Browser support for <form> submission HTTP verbs is limited to GET
and POST. Rails currently works around this limitation by
constructing <input type="hidden" name="_method" value="VERB"> which
serializes _method="VERB" to the FormData.
To support varied HTTP actions within the same form, this commit
intervenes when a form.button formmethod: "..." call is made during
form construction, and translates any formmethod: value to the
corresponding work-around version.
