Message selector

[bitsofinfo]

Would ask that issue #83 be re-opened

@see http://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/SQSExamples.html
http://docs.aws.amazon.com/IAM/latest/UserGuide/ManagingPolicies.html#AddingPermissions_API

You can create a policy with a conditions stanza (example below). So maybe a way to convert the message selector into a call that would apply that as a policy change on the SQS queue?

"Condition" : {
"DateGreaterThan" : {
"aws:CurrentTime":"2009-01-31T12:00Z"
},
"DateLessThan" : {
"aws:CurrentTime":"2009-01-31T15:00Z"
}
}
