Use prefix matching in ZMQConnector

- Control/Signed/FSMAwareEventHandler unit tesztek
- command_handler dict automatikus generálása
- frontend keyup ne hallgasson már a nyilakra meg ilyenekre
- CommandEventHandler humble object + tesztek
- terminalba írás ideiglenes letiltása
- ha nem kell egy komponens ki lehessen venni
- pipe, ami aláírja az üzenetet, amit beleküldünk
- legyen pötyögtetés a message queue elején
- a queue thread-jét lehessen join-olni várakozás közben is
- PipeConnector nyissa meg a már előtte is létező pipe-okat
