Added document string; changed back some method param types of interface Console from 'any' to 'string'; Removed static members from interface instance definition; Sorted overloads of 'addEventListener's by event name; Removed unnecessary declaration of the 'addEventListener' method in some interfaces; For method overloads, moved the most generic ones to the last; Removed named-constructors and dictionary interfaces from webworkers.generated.d.ts (including Audio, Image etc); Made all string overloads of 'getElementsByTagName' lower case for consistency.
