   Simplified browser sniffer. Growing more complex, though.
   
   Please avoid using this whenever possible: it's much better

   - Drawer speed control (NS6 was way too slow)
   - Mouse location detection (IE5/Mac returns locations relative to the div, not the window)
   - Profile drawer (NS4 can't write profile data into the form)
