// -----------------------------------------------------------------------------
//   customizable open window command

// r = resizable, s = scrollbars, t = toolbar, l = location, d = directories
// the order for rstld doesn't matter
// resizable default is yes, scrollbars,toolbar,location,directories defaults are no

// usage examples:

// openWindow('mylink.html,300,300,s,popWindowName'); -- pops a 300x300 window 
// with scrollbars named "popWindowName"

// openWindow('mylink.html'); -- pops a default size (hardwired to 640,400) 
// window to mylink.html

// openWindow('mylink.html,,,tlr'); -- pops a default size window to mylink.html 
// with tool and location bar that is NOT resizable
// NOTE: notice that in the example above there are two commas after the URL
// they're required in this case because we're adding the 'tlr' options
// commas without values will just pick up the default 640x400 values, or you 
// can change them to whatever. The rule is only the URL is required, but if you
// change a value downstream, then you need to fill in the values between the 
// URL and the value you're changing (even if it's only with a comma).

// It now centers the pop-up.
