/*********************************************************************************************\

    MassRollback

    On a user's contributions, add a portlet link for mass rollback to the toolbox. When the
    link is hit, a dialog will pop up, and the script user can configure three options:

     * Mark edits as bot edits (exclusive to sysops, g-sysops, g-rollbackers, and stewards)
     * Hide username in the rollback summary
     * Add target pages to watchlist
    
    When the 'execute' button is hit on the dialog, all visible rollback links on the page
    will be resolved at one fell swoop in accordance with these configurations.
