Add "number" type function for Textfield

[Janiczek]

In similar vein as Textfield.email or Textfield.password
Is tis a good idea, or is there some other canonical way? (regexes and validation?)

Missing the ability to set the type of the input, too. "date" and "time" would be great!

[FabienHenon]

And "tel"

Is there a workaround for this?
Because I'm about to fork the project for this feature :(

Can say that I would love an ability to set the type of an input to date.

Currently, I'm trying to get the following code to work, but it has no effect for some reason

Textfield.render Mdl
        [0]
        model.mdl
        [ Textfield.label "Date input"
        , Textfield.floatingLabel
        , Options.onInput SetDate
        , Options.input <| [ Options.attribute <| Html.Attributes.type_ "date" ]
        ]
        []

But the type resolutely stays as text.

This will only come in v9. I will close here and track progress in #335.
