added docstring as a property to the module class that comes out of
AST (so the free strings no longer appear an the first element in the
parsed files).

python/cpython#46 or bpo-29463

added docstring as a property to the module class that comes out of
AST (so the free strings no longer appear an the first element in the
parsed files).

* FIX: install on python 3.7

python/cpython#46 /
https://bugs.python.org/issue29463 move the module comment into the
AST node and hence out of the tree which means the 2nd entry in the
tree is now the import rather than the `__version__` string.

Adds nightly on travis.

* BLD: update python tags in setup.py

* CI: switch to 3.7-dev

* CI: allow failure on 3.7 dev

* Pin pytest to latest version 3.3.2

* Pin pytest-asyncio to latest version 0.8.0

* Pin pytest-aiohttp to latest version 0.3.0

* Update cherry_picker from 0.2.5 to 0.2.7

* Pin aiohttp to latest version 2.3.9

* Pin gidgethub to latest version 2.4.1

* Pin cachetools to latest version 2.0.1

* Pin requests to latest version 2.18.4

* Pin redis to latest version 2.10.6

* Pin celery to latest version 4.1.0

Email generators had been incorrectly flattening non-ASCII email
addresses to RFC 2047 encoded-word format, leaving them undeliverable.
(RFC 2047 prohibits use of encoded-word in an addr-spec.)
This change raises a ValueError when attempting to flatten an
EmailMessage with a non-ASCII addr-spec and a policy with utf8=False.
(Exception: If the non-ASCII address originated from parsing a message,
it will be flattened as originally parsed, without error.)

Non-ASCII email addresses are supported when using a policy with
utf8=True (such as email.policy.SMTPUTF8) under RFCs 6531 and 6532.

Non-ASCII email address domains (but not localparts) can also be used
with non-SMTPUTF8 policies by encoding the domain as an IDNA A-label.
(The email package does not perform this encoding, because it cannot
know whether the caller wants IDNA 2003, IDNA 2008, or some other
variant such as UTS python#46.)
