  Changelog
  =========
  - fixed bug in IE
  - added handleClick argument (default to false)
  - added stronger typecheck for the regexp variable
  - fixed variable scope of "handlers"
  - now using builtin hash window.location.hash instead of full URL
  - removed array support to make the code more consistant and less error prone
  - added "end" method to allow jQuery object chaining
  - the click handling now *returns* the callback function so it can halt event propagation
  - the API changed so I moved to version 0.4
