Update to JavaScript DOM Text Clips

Many more objects properties and methods have been added to JavaScript DOM Text Clips. As well as being useful as text clips, it also serves like a reference - it can be used to see if a certain element supports a method or property as defined by the W3C. Any of these properties or methods, if used appropriately (i.e. don't use 'href' on a 'table' element for instance), should work in any DOM1 compliant browser.

Popup Window Countdown (JavaScript)

This code opens a new popup window that contains a timer that counts down, then closes the window when it reaches 0.
