Patch to support DateTime in serializer

[Geert De Peuter]

I hope this diff will be usable.
This is a unified diff against AMF 1.9 beta 2.
After applying this patch, you will be able to send php native DateTime objects back (so they will be serialized properly).

Hopefully this will be incorporated in the codebase.
The intval($d->format('u') / 1000) would only be useful for people who have their dates created with microsecond precision.

Geert, I cant thank you enough for this! Really helped me a lot.

[Geert De Peuter]

Any chance this is going to be picked up for a later release ?
