VideoHub naming update

VideoHub naming update

Minor change: I’ve tweaked the names on the VideoHub (40×40) to shorten them from “Stagebox 1” / “Floorbox 1” to “SB01″/”FB01” – This naming function now mirrors the names in the physical floorboxes themselves, and puts greater emphasis on the port number (111, 113 etc) – which in my mind is the most important bit of information, although granter it doesn’t indicate whether it’s an input or output

Any issues please let me know though
