New Port for ACE-6.0.4

[Ladislav Jerabek]

Hello.

This is my first port submission, so I hope that I will do it right. I
modified patches from ACE-5.5.2, create port for ACE-6.0.4 and attached the
SHAR file.

Let me please know, if I should fix anything.

Thank you.

Best Regards,
Ladislav Jerabek
