The code has been updated to meet
the requirements of the updated V8 engine
as provided by io.js.

In some cases additional EscapableHandleScope
has been provided.

SassValueWrapper<T>::New has been changed:
in case of instance construction via
the function call "sass.types.Color(0,0,0)"
instead of "new sass.types.Color(0,0,0)"
the "new" part is no longer executed by
falling through. This should not be necessary
because the constructor is called by
the NewInstance call anyway.

This fixes the following error:

FATAL ERROR: v8::Object::SetAlignedPointerInInternalField() Internal field out of bounds
