This patch sets the environment variable LANGUGE to 'en', meaning English translation is used for outputs. The string comparisons in test_gpg_binary_version_str failed otherwise when using a non-English locale. Another choice may be to set LANG=C to avoid locales all-in-all.
* ADD docs/change-license-emails.txt, which includes email exchanges between
myself and intrigeri, including links to Debian and LEAP mailing lists with
arguments for and against using AGPL for a library.
* CHANGE license header for all files.
* CHANGE LICENSE file and gnupg/copyright.py to use GPLv3+ text.
* Add GPG._generated_keys as an _utils.InheritableProperty class for storing
a configurable (even by subclasses of GPGBase, without property overrides)
subdirectory of whichever directory gnupg.GPG.homedir is set to. This
subdirectory can be used via the 'separate_keyring=True' option to
gnupg.GPG.gen_key_input(), which will switch temporarily to new pubring.gpg
and secring.gpg keyrings during key creation, and upon finishing creation
of the new key, will ask for the new key's fingerprint, and move the
keyrings into this GPG._generated_keys directory, renamed in the format
"<GPG.homedir>/<GPG._generated_keys>/<fingerprint>.[pub|sec]ring.gpg".
