Modified Iad

I have modified the Apple Internet Address Detectors and created the MIAD detector/action set. All of Apple's original functionality has been preserved. Modifications include: * added detection of "www.site.dom" format URLs * cleaned up detection code for readability * added a list of all top-level domains (as of 6/99) for addition to site detections MIAD is also available at the Apple Data Detector Depot, a site specializing in the development and distribution of data detectors.
