Unable to parse multi dimensional arrays with more than 2 levels

This bug entry corresponds to pull request https://github.com/apache/cordova-osx/pull/29

Detail:

As we send arguments with commands to objc from javascript, current implementation "convertWebScriptObjectToNSArray" and "convertWebScriptObjectToNSDictionary" converts Javascript objects to NSArray/NSDictionary but it doesn't parse the children at 2nd level and show zero elements in there.

Input:

x = { a : { b:

} };

Output:

x = { a : { b : { } } };

Solution:
Replace the current method with "[[webScriptObject JSValue] toArray]" which a native method of apple webkit solves the problem.
