BUG#:473
BRANCH: 2.3.2
TITLE: rSystem.cpp getSystemCreationClassName() returns empty
DESCRIPTION: This static method was provided in system.h but only provided useful information for the HP unix system.  We simply changed the systemUnix.cpp and systemWindows.cpp to return the string CIM_Computersystem, as was done for HP Unix.
