Displays themed installer output and ends the page request.

Installation tasks should use drupal_set_title() to set the desired page title, but otherwise this function takes care of theming the overall page output during every step of the installation.

Parameters

$output: The content to display on the main part of the page.

$install_state: An array of information about the current installation state.
