can't use aws buckets with periods in the name

[earlh]

see discussion here:
boto/boto#2836

eg boto won't work with bucket 'a.b' but will with 'a-b'; requesting a key for any bucket with a period in the name returns None

Common case :( People likes to use their domain name as a bucket.

Yeah, guess how I found it :D :D. My previous naming scheme for buckets was initials.project. There went two hours ending with "I'm copying and pasting the goddamn code sample exactly as written".

Unfortunately, there doesn't seem to be an easy solution; the most direct one is editing ~/.boto but that doesn't necessarily work. Worse yet, ~/.boto is also used by gc/gsutils, and I'm not sure if the change is compatible with both. That's at bare minimum a pain for dev.

Fixed with #651 by migrating to boto3, which has that bug fixed.
