//----------------------------------------------------------------------------------
// Plugin for jQuery 1.2.x to set up external links to open in a new window
//
// All links are scanned and any non-local links are modified to use window.open()
// to open their locations in a new window.
//
// To start up this functionality, issue the init() command, passing an optional
// array of strings specifying additional exceptions that will open in the current window.
//
// custom - Array of strings to add to the exception list
//
// $.externalLinks.init();
// $.externalLinks.init(["othersite.com", "www.whatever.com"]);
//
// jQuery data can be assigned to individual anchor tags to store specifics for the
// window to open. You can set a class on the link to facilitate different options
// for a specific type of popup.
//
// name - The name to assign to the window for this type of popup
// options - Set the appropriate window options
//
// $("a.contact")
//     .data("window", {
//         name: "ContactInfo",
//         options: "toolbar=0,location=0,directories=0,status=0,menubar=0," +
//             "scrollbars=yes,resizable=yes,top=(20),left=(20),screenX=(20)," +
//             "screenY=(20),width=400,height=300"
//     });
