InvalidParameterCombination error with Volume Type = General Purpose (SSD) AMIs

Hi StarCluster Team:

When using an AMI with volume type = General Purpose (SSD), I get (in debug.log):

The AMIs in question are clones of fully functional volume type = Magnetic

It was pointed out to me that this was already requested in issue #264. Closing.

After further consideration, the two issues --volume type selection during volume creation (#264) and this error -- should remain separate. This issue is a bug, the other is a feature request.
