Customize MediaWiki installation with Login Screen

Project Summary: I have a MediaWiki installation that I will be using for my business as a private wiki for internal staff use only. This project will involve customizing MediaWiki ([login to view URL]) by adding a login screen to the root subdomain - ie/ [login to view URL] so that a wordpress style login box (see: [login to view URL]) appears requesting the user to sign in. Only on successful entry of username/password should a user see any content on the wiki. Additional Details: 1. The Wiki MUST be completely hidden and not be indexed by google or to anyone unless they are logged in. 2. The login form should automatically log the user into their wiki account so they can add/edit/view content 3. New users created in the mediawiki admin account management section must be added to the new login screen automatically MOST IMPORTANT - This modification must be provided as a "PATCH" - For delivery of this project I require a .ZIP with all the files in the correct directory structures so i can simply upload via FTP overwriting existing files as required - then following any additional steps required. ALL INSTALL INSTRUCTIONS MUST BE DOCUMENTED. Any other questions please send me a PM.
