Got rid of that horrible fixed size switch in boost_any_to_qvariant.hpp
Added some debug macros to help in identifying what outputs what
Fixed a bug where a client that connects to a server with existing radios would not update its own radio_list
Changes the pipeline to allow mutliple clients to connect.

It works but gstreamer timestamps are not yet synchronising causes some emergent behaviour
Extends the test key to also select the first radio.

It is an ugly hack but it helps with debugging tremendously. The reason I have to sleep is to wait untill something is there to click, this race condition is impossible if you are the end user and you wait for the radio list to fill to click an item.
Added mute functionality.
