  Created by Gollum from an idea/suggestion/request at us.o by @Seph_VIII
  Expanded upon by @Mithrandir(us.o)
      - with help from @Dr. Evil(de ff-user-group)
          ... max links to open, conditional button display, timeout delay, extra button styling, windowOpen fallback for GM_openInTabs
   Gollum: added quick element check for vB board, plus x-browser support - tested in Opera(9.25) and IE7(IEPro), plus option to ignore timeout delay.
