show in GUI if a powerboard can be used to build a module (see screenshot; see !178). NB: The PB_NOISE test is skipped for this atm, as it is still in a development stage.
for each test, show what the expected ranges of a failing value are; print this to cout, but also write this into the test comments (see second screenshot; see !180). WARNING! There may be some bugs, as this required many small changes, where one can easily get confused. I double checked everything, but there is no guarantee, yet.
