The below changes are required in the Titanium update wizard to improve the user experience -
1) Change the wizard image on the top to look like an installer image.
2) Add user id field to the password sudo page.
3) Gray out 'Titanium SDK' field in the Installer main page to indicate that it is mandatory and as the user can not de-select it. Also, the text of NodeJS should dynamically switch to 'NodeJS (required)' if the user selects any of components (acs, alloy, or cli).
