Show Password feature not appearing on WP login page

[alanjacobmathew]

Accessing the login page directly from ​https://login.wordpress.org or ​https://login.wordpress.org/?redirect_to=http://core.trac.wordpress.org/ by default, the show password feature is not appearing.

The show password feature only appears when the login page is ​https://login.wordpress.org/wp-login.php

In 11378:

Login: Disable the Core login language selector, through a rather low-level filter.

There are no filters available to disable the login language selector, so instead we make WordPress believe there are no languages available on the front-end wp-login.php display, which hides the selector, but still loads our custom login localisation files.

See #5850.

In 11379:

Login: Replace the call to wp_login_form() with a static form so that we can customise the content.

wp_login_form() isn't the same as wp-login.php and isn't as easy to customise; By removing it we'll be able to add things that wp-login.php has such as a show password button.

See #5850.

In 11380:

Login: Add a 'show password' / 'hide password' button to password inputs, for consistency with wp-login.php.

Fixes #5850.
