namespaced @property/@method cleanup Some files had new YUI.add() metadata property ordering, resulting in new -min files. No functionality was changed.

Update _COMMON_LENGTH immediately Not sure why I was waiting until the next call to stringify to take advantage of new special character fast pathing. Must be the heavy drinking.

Break out common special chars from fn replace. Per suggestion from Brian Kaull, the performance of string.replace(regex, fn) is far slower than string.replace(regex, string), so for common special chars, such as \ \n " etc, preprocess strings with specific regexes targeting these characters, using the replace(regex, string) signature. Then process the string with the generic replace(regex, fn) for other special characters. So, more calls to replace are made, but very few should trigger replacement from the generic replace(regex, fn). Additionally, add adaptive caching of special chars to their targeting regex if that char commonly appears in strings. Base the cache threshold on new Y.JSON.charCacheThreshold config.

Add deprecated flag to dateToString method. Just use a replacer. The JSON util will follow spec as much as is reasonable.

Testing Y.config.win before use to support a headless environment.
