Updated slow control initialization buttons to check the crate power first.  Need to change qdebug message to msgbox
Updated buttons to recognize if relevant channel on crate is on.  Changed initialization button to set the ids of the micros before initializing
split hvcontrol to address turning on bias by cartridge separately - note: not flexible for future cartridges
changed the setHV for the bias voltage to deterministic on/off from toggle
added function to get the slot power status from the floating board for the cartridge
