Renaming CentOS builds from cc7 to centos7 (AtlasCMake-00-01-57)

	* Changed the "short name" of CentOS to "centos" from the
	  previous "cc". As that's the new SFT convention.
	* Tagging as AtlasCMake-00-01-57

	* Removed the debugging message that I left in FindGaudi.cmake,
	  while debugging why it wasn't picking up the right RPM version
	  in the nightly. It wasn't causing any problems, was just printing
	  an annoying message. (Which was highlighted a lot more by
	  QtCreator.)
	* Tagging as AtlasCMake-00-01-56
