Fixed LiveViewer Roi coordinates mistake.
Remove attr working_energy, now only use energy_threshold (in keV)
which calls Camera.setEnergy(). PilatusCamera.setEnergy() manages old and new
version of camserver
I added an attribute "normalize" to make optional the normalization of the
flatfield image. This needs the last fix in control/software_operation/include/SoftOpId.h
for setFlatfieldImage() function
Added .edf.gz as Taco device file format i suffix (in addition to .edfgz)
