Add getTrackParticlesVec helper. (xAODEgamma-00-01-40)

	* Add getTrackParticlesVec helper.
	* Apparently the getTrackParticles which is there to
	* help with the isolation  and thus returns a set,
	* has led to a "confusion" as the set does not retain the original
	* ordering. The current helper has to stay as it used by the isolation.
	* Added another one that returns a vector and hopefully people will
	* either use the methods from the interface or read the comments on the methods.

	* Root/xAODEgammaCLIDs.cxx: Add this file to ensure the storegate+class_def stuff is encountered at compile time ... necessary
	to avoid problems with address remappings etc (need to know the SG::BASE structure early!)
