Adding new tests developed over the last months at DESY, containing various Dac scans, PH functions etc.
Merge branch 'devel-DTB' into desy-tests

Conflicts:
	src/psi46expert/MainFrame.h
Temporarily remove PHscan test, uses different decoder which is not in yet.
Remove PHscan temporarily, see commit before.
Add Cals() to Test.cc/.h, used in PHvsCals.
