Documentation tweak.
Modifications to the var class to make it more javascript-compatible. Changed the handling of array types to be a shared, ref-counted array rather than being copy-by-value. Added an "undefined" type. Updated the native method invocation functions to be static (the old version used class methods) and to provide a 'this' object which may be different from the DynamicObject on which it's being invoked (this is to deal with derived classes)
Added a method JSON::parseQuotedString
Fix for CoreGraphics multi-rectangle gradient drawing.
