Automatically detect firmware type and possibly device type

[zach-hartwig]

It would be much easier on the user if ADAQAcquisition automatically determined the firmware type, which should be possibly by accessing specific registers/CAENDigitizer functions when first connecting to the device. This would alleviate easy mess-ups on the part of the user. It may also be possible and preferable to use the CAEN provided enumerators to automatically identify the board/device type as well, alleviating the user of yet another place to make mistakes.

Implemented the ability to auto detector CAEN digitizer firmware type and dynamically configure the code accordingly. This should alleviate problems. Firmware type is now output to the connection screen upon successful connection. All widgets and code removed.

I have decided to force the user to specify the board type, however, as this is useful to make the user think about what they are connecting to. This could change in the future, but I will close the issue for now.
