Description:
When we install mediawiki, If I give the administrator username and password as a same string, it reports as an error in the last page of installation and asking me to go back to change this.

The validation and similarity check should be done on the same page and reported in that page itself before moving to next page.

Example:

http://localhost/mediawiki-alpha/core/mw-config/index.php?page=Name

Administrator account

Your name: shrini

password: shrini
passoword again: shrini

Get the error only in the following page.
http://localhost/mediawiki-alpha/core/mw-config/index.php?page=Install

error message:

Internal error when setting a password for the admin "Shrini":

Your password must be different from your username.

This should be checked using javascript and displayed in the same "page=Name"
page.

Please fix this.
