/* Determine if banner should be shown based on:
 *  A) if user has enough edits
 *  B) if user hasn't seen banners too many times
 *
 * Parameters (names should be self-explanatory)
 *  min-edits
 *  views-cookie-name
 *  max-views
 *
 * View counter cookie expires after being untouched for 60 days
 * which ought to be long enough for all non-fundraising campaigns
 *
 * Result is stored in mw.centralNotice.bannerData.hideResult as usual
