py-trustme: updated to 0.5.0

Trustme 0.5.0:

Features
Added CA.create_child_ca() to allow for certificate chains
Added CA.private_key_pem to export CA private keys; this allows signing other \ 
certs with the same CA outside of trustme.
CAs now include the KeyUsage and ExtendedKeyUsage extensions configured for SSL \ 
certificates.
CA.issue_cert now accepts email addresses as a valid form of identity.
It’s now possible to set the “common name” of generated certs; see \ 
CA.issue_cert for details
CA.issue_server_cert has been renamed to CA.issue_cert, since it supports both \ 
server and client certs. To preserve backwards compatibility, the old name is \ 
retained as an undocumented alias.

Bugfixes
Make sure cert expiration dates don’t exceed 2038-01-01, to avoid issues on \ 
some 32-bit platforms that suffer from the Y2038 problem.
