set email input type to email #94

I haven't tested how it actually looks in the frontend.

email: HTML5
A field for editing an e-mail address. The input value is validated to contain either the empty string or a single valid e-mail address before submitting. The :valid and :invalid CSS pseudo-classes are applied as appropriate.

We could also set it to required.

required HTML5
This attribute specifies that the user must fill in a value before submitting a form. It cannot be used when the type attribute is hidden, image, or a button type (submit, reset, or button). The :optional and :required CSS pseudo-classes will be applied to the field as appropriate.
