New classes for user and group names provide a convenient way to access
the uid and primary gid of a user / gid of a group. The classes also
provide chown() and chgrp() methods to simplify common operations.
The wrappers are subclasses of builtin str type and behave like ordinary
strings with additional features. The pwd and grp structs are retrieved
once and then cached.
