IDL: Support 'stringifier' keyword
Usable in one of these forms:
stringifier;
stringifier DOMString ();
stringifier DOMString name();
stringifier attribute DOMString name;
All cause a toString() method to be defined on the interface automatically.
The first two are equivalent, and call CPPClass::toString() to retrieve the
string value. The latter two use CPPClass::name() to retrieve the string
value and also declare a regular attribute and operation, respectively.
Changed all simple "DOMString toString()" occurrences in IDL files to use
"stringifier" instead.
