python bindings: export secret keys
* The holy grail: a function to export secret keys.
* GPGME will still invoke pinentry and gpg-agent as usual to authorise
the export.
* Mostly similar to the two previous export functions for public keys
except that it will return None if the result had a length of zero
bytes. Meaning that the difference between the specified pattern
(if any) not matching available keys and an incorrect passphrase is
not able to be determined from this function (or the underlying one
for that matter).

python bindings: export public keys
* Added functions for exporting public keys to gpg.core in both
complete form and in minimised form.
* Rather than letting people need to worry about the export modes we
are simply separating the functions as people would be more familiar
with from the command line usage anyway.
* Functions added for Context are: ctx.key_export_minimal and
ctx.key_export as the default or full export.
