/* Contributions (top) edit hider, version [0.0.3] 
Originally from http://en.wikipedia.org/wiki/User:Splarka/hidetopcontribs.js

On Special:Contributions button hide all pages the current user is top contributor on

Notes:
* If on an offset or dir URI, one cannot reliably determine top edits, so it isn't active.
