All changes from daq-master (mainly AcquDAQ, but also affecting analysis)

Before we decide to pull this merge into A2/master, I'd like to see some people to test it. Just checkout the branch neiser/daq-upgrade to do this! It should work just fine... After the beamtime, I will probably then test it on the actual DAQ system.

The fact that the merge was pretty easy (see last commit), does not mean that it actually works as expected.
