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.

SW-32: tried to merge https://svn.astron.nl/LOFAR/branches/SW-26_WinCC into trunk, but there was too much svn merge hell due. So, ended up merging the branch into trunk using meld manually. Committing this manual merge now in this one commit

Task #11384: Increased ObservationControl timer for sending FINISHED/ABORTED from 10s to 300s to allow more time for FeedbackService to put feedback in OTDB before MoM retrieves it.

Task #10099: GCFCommon (and prod/test) handled childstate the old way.  repaired this, added REPAIRED and MISSING to states

Task #10099: GCFCommon new added to svn, svn is rollout also on the gui machines, rocr3 and smu, and there are no symlinks installed there, so we need to keep it.  The scripts that install the Navigator on test or production systems need to be changed to first remove GCFCommon.ctl b4 creating the symlink
