Major Changes
-------------
- Changed the default expiration date on generated keys from never to 3
years after created. This is both for the integrity of the keys, but
also as a courtesy to the key community by not recklessly creating
keys that never expire.
- Added ``revoke(uid)`` method, which revokes the key with matching
``uid`` if the secret key is owned by the user & the key passphrase
is stored in the instance’s ``passphrase`` attribute.
