Release 1.2.0

This release introduces new single host and parallel clients based on ssh2-python, using the libssh2 C library.

They offer significantly enhanced performance and reduced overhead in CPU and memory usage compared to the current default clients.

See read-me for a quick how to use. API is mostly identical for the two parallel clients, see API documentation for details.

No backwards incompatible changes have been made.

Feed back and bug reports on the new clients are most welcome.
