This should only be minor tweaks.

Hack to determine whether the display is installed or not. If not avoid trying further communication by setting the displayPresent flag to FALSE

Can now activate ADAFRUIT backpanel. Still lots to do. Need to add switch to not use display if tabletop mode

Documentation

Added debug to I2CuHal2 to indicate when a slave fails to ACKNOWLEDGE (useful to see if a device is responding at all). Also started to expande the functions available for the LCD09052 display.

In Python scripts, added code to control the PMT voltage using a steering card in the config file. Same name used in EUDAQ. Also added a INI steering card (vCtrlMax) used to define the maximum control voltage for the PMTs. This is only needed for powermodules specifically hacked, like the one for Thomas Bergauer.

Hopefully all right.
