filter target in connection windows

Created by: mbonani

often lot of target are displayed that are not relevant (BT com port, serial port on Linux). Also with zeroconf and simulator you can have a big list. I know that we want to keep it as general as possible but could we imagine check boxes to set up a filter like: "show all", "show only local", "show Thymio" "show simulated robot" "show network robot" "do not show unknow device" etc. to decide what is generic or not, check box can perhap be exclusif or not,
