Originally from http://en.wikipedia.org/wiki/User:Splarka/quicktag.js

Notes:
* Needs to be defined in your user js like so:
  var insertTagButtons = [
    { 'label': 'Speedy',
      'open' : '{\{speedy|',
      'close': '}}',
      'def'  : 'crap page'
    },
    { 'label': 'Nom',
      'open' : '{\{eat}}'
    }
  ];
** Closing tag and default text are optional (if omitted it is treated as a parameterless tag).
