	* Updated the code to only build the C++ plugins of FastJet.
	  To avoid Fortran linking problems in AnalysisBase.
	* The code now makes use of ${CMAKE_FILES_DIRECTORY} to
	  organise the build directory a bit more neatly.
	* The installation should no longer kill the project's
	  installation in case FastJet fails to compile.
