API 2013-02-01

Hi Lincoln,

Here's a quick update for the 2013-02-01 API functions.

When using the CopyImage call, if you run a DescribeImages on the AMI being copied, the snapshot IDs are not listed in the result until the copy is complete.  I opened a ticket with AWS requesting this be changed and they report that it has been sent to the engineering team for implementation -- good news.  Without this it is impossible to automate a way to determine progress of the copy.

I'm holding off on RDS until you publish the refactored code -- I figure it will be a lot easier for you to merge that way.
