TWC Patch 2014-08-28

Apologies for the large PR again. In the currents of change I haven't been able to get a process in place to do PRs per patch/feature. As of tomorrow that process should be in place though, so you should be seeing much smaller patches from us.

Changes:
- New operation to the MachineImageSupport: copyImage, which copies given image to another region.
- Main property to RoutingTable -- allows identification of main/default routetables over others.
- Support for attributes (crossDataCenter, timeout, etc) on load balancers.
- Add/remove listener support to load balancers.
- Ability to set firewalls when creating load balancer.
- Add health check info to LoadBalancer.
- Add volume info to machine image.
- Add set/list notificationConfigs to AutoScalingSupport.
- Added synchronous call to create tags.
- Deprecated subnetIds property (comma separated string) and added new String array for subnetIds in Scaling Groups.
Sure thing I'll update my devs with the jar you provided.  I'm not sure we're all on idea or not, but I think everyone can view the settings within the jar.

@eyaroslavtsev -- while you are making the other changes, would you mind changing this back please.  Thanks.
