SW-642: Print command line arguments separated by spaces, instead of as a vector, for easier readability and use.

SW-90: made some changes in the cmake/lofar find_package logic: when we want the BUILD_DOCUMENTATION, then the REQUIRED option is removed from the (lofar)_find_package calls. This allows cmake to finish configuring and generating Makefiles, and allows us to build the target doc, but probably not parts of the code when external packages are not found. That's ok, and intentional.

Task #8629: Replaced all occurrences of 'install(PROGRAM ...)' with 'lofar_add_(s)bin_script(...)', except where DESTINATION was not (s)bin, or where extra options are passed to the install-command.

Task #6883: Do NOT wait for RSP_UDPBITMODE and RSP_UDPSPLITTER when setting either, since the boards can be in the correct state already due to an async update of state.

Task #8365: removed version cmd and bitmode from startup sequence and add 1 sec wait in ClockControl
