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
