v3.8.0

Ruby mogilefs-client 3.8.0

Mostly documentation updates and test cleanups.  Nothing interesting
for the regular client, but the admin client now shows the
checksum-related fields in get_devices.

Most notably, there's a public-inbox for those who don't want
to subscribe to the MogileFS list:

	mogilefs-client-public@bogomips.org

Archives are at: http://bogomips.org/mogilefs-client-public/

There is no new mailing list subscription, it is only a
public-inbox.  Cc-ing the MogileFS list at mogile@googlegroups.com
is encouraged if you do have a subscription.
