  Functions and classes to make popup windows more useful.

  Keep a consistant list of Window.open features, and implement 
  "dependant=yes" type behaviour (Netscape only) for all browsers.

  See The Definitive Guide P673 for a list of features.

/* nothing happening yet: just bring the window to the foreground

  Call this as the onclick handler in an <a href=... target=...> tag. It 
  will use JavaScript to open the window with the requested features, and
  return false to stop the browser following the link. 

  This allows more control over the opened window, but allows links to be 
  followed by browsers that have JavaScript switched off.
