ZF-8646: Add copyObject() method to Zend_Service_Amazon_S3

Description

Copy operations are supported by the S3 REST API.

So, this patch adds moveObject() and copyObject() which exploits this capability.

Comments

Patch with tests attached.

Jon, I understand you are project lead for this component so I am assigning to you. Can you please review & apply patch if acceptable? This will then allow the SimpleCloud API to do "cheap" copy/move on S3 as well.

Corrected patch - fixes naming issue in the unit test

Applied in r22454 , so tagging fix version as next minor release.

Resolving, as patch was applied to trunk.
