        Delete window.WebCL property as this must not be exposed to JS.
        Issue #257

        Reviewed by Antonio.

        As a singleton object is exposed to JS via window.webcl we must not
        expose WebCL interface to WebCL.
        Adding "NoInterfaceObject" in WebCL.IDL.

        No new tests (OOPS!).
