Version-> 0.2.1-SNAPSHOT

Added describe-availability-zones, report-availabilty-zones

run-instances now accepts keywords for the ami-id argument,
    and the :keyname, :group-ids, and :group-names options.

run-instances now has the following options:
    :placement <az>, :monitoring <true>, :disable-api-termination <true>
    :instance-profile <profile-name-or-ARN>
    :ebs-optimized {true/false} defalt false
    :shutdown-behavior {stop,terminate}

Added describe-security-groups function.
Add support for com.amazonaws.auth.InstanceProfileCredentialsProvider
based credentials via 'def-cred-instance' function.

Restore report-instances lookup of instances if none are specified via
:instances or :ids (I recently broke it).
