Refinements to different parameter formats

Clarified test cases for OpenThings.Message()

Started writing unittest harness for new OpenThings.Message abstraction

Message.get() implemented and tested with paramid keying

Started to think through a better message abstraction

Started to think through a better alterMessage ...

characters that can be used in an identifier need checking

Improved separation of test harness messages

Major tidy up of test harness and lifecycle methods

Moved test harnesses into separate _test.py modules

More representative synthetic data added to FSK receive test

Poked a synthetic switch on message down the MIHO005 receive pipeline

Started to flesh out the MiHome receive pipeline

Spec'ed interface for OOK decoder

Deprecated Messages due to import race with Devices. ...

Template messages (which are cloned with create_message) now in Devices.

Commissioned a tx path for MiHome adaptor Plus. ...

This is a temporary path, but it generates the correct message

LegacyDevice tx path commissioned end to end

Most of the OnAir interface coded or spec'ed now
