#178 s3cmd does not work with http 307 redirection

[Yong Li]

When a redirection response is received, s3cmd can get the hostname in the conneciton map correctly if bucket name dns support is not configured.

def get_hostname(self, bucket):
    if bucket and check_bucket_name_dns_support(self.config.host_bucket, bucket):
        if self.redir_map.has_key(bucket):
            host = self.redir_map[bucket]
        else:
            host = getHostnameFromBucket(bucket)
    else:
        host = self.config.host_base

The bucket name dns support is not configured because we use path style access instead of virtual host style.

For example,

curl http://10.32.172.184:9020/bucket1/key

<error>
TemporaryRedirect
<message>Temporary Redirect</message>
<bucket>bucket1</bucket>
<endpoint>10.32.169.214:9020</endpoint>
</error>

s3cmd -d -v ls s3://bucket1/

Typo: should be "can NOT" get the hostname correctly.
