Updated client side network handling (use more signals/slots for basic interaction)
* removed some no longer needed code
* no longer provide methods on ClientController to receive internal network clients, everyting is handled by ClientController
* do not create member objects on stack to make it possible to move Clientcontroller into a different thread - use lazy loading for those objects
* client side start/stop works good now

TODO:
* it still doesn't work to see own video on reconnect.
Added script to execute cmake on windows vc10 x64
