Input type="email"

[johnbillion]

Text inputs for email addresses were replaced with email inputs in [20168] but reverted in [20196] due to poor client-side validation by Chrome 17 and Firefox 10, however we've had input type="email" on the registration form since [18763].

We should:

1. Test the current state of client-side validation.
2. Either introduce email inputs in the admin area or revert [18763] depending on the results of point 1.

See http://core.trac.wordpress.org/ticket/17863#comment:25 for the email input validation issue.

I went through all of wp-admin. That wp-login.php was not reverted was indeed a mistake.

Setting the forms to novalidate should be sufficient, if that remains a concern. Context-sensitive mobile keyboards is, in my opinion, more important than validation.

Changes email to text on wp-login.php (in case we don't go with the novalidate route)

novalidate option using email instead of text (needs testing)

In 22413:

Revert type="email" on the registration form to avoid validation issues. see #22183.

Let's try to bring these back (sans validation) in a future release.
