Reviewed by Sam Weinig.

* Source/WebCore/bindings/scripts/IDLParser.pm:
(parseDefaultValue): Accept = {} but return undef, resulting in
the current behavior when no default is specified.
* Source/WebCore/bindings/scripts/test/JS/JSTestObj.cpp: Updated
* Source/WebCore/bindings/scripts/test/TestObj.idl:
Added test cases for dictionary attributes with default and
optional dictionary to operation with default.
