Cryptoconditions

------------------

Changed
^^^^^^^

* ``crypto.ed25519_generate_key_pair()`` now supports an optional keyword argument ``seed`` to support deterministic generation
of a keypair from a seed.
Example use: ``crypto.ed25519_generate_key_pair(seed=seed_value)``
Note that the value of ``seed`` must be a 32-byte bytes object.
Thanks to external contributor excerebrose for adding this functionality in pull request 487.
* Changed setup.py to use ``PyNaCl~=1.1.0`` again, because 1.2.1 was breaking software that uses the cryptoconditions package.

which contained the message "Update changelog for 0.7.0 release".
