- Fixed the problem that the Fortran could be optional.  
- Fixed Cling option in core/meta package
- Fixed libraries to be linked when 'explicitlink' is enabled in cint/ROOT
- Generating ROOTConfig.cmake for use by CMake projects using ROOT.
  It is placed under ${CMAKE_INSTALL_PREFIX}/cmake directory 
  after installation or at top level of the build directory if using
  the build area.
  Project clients just need to add these lines in their CMakeLists.txt file: 
      find_package(ROOT REQUIRED)
      include(${ROOT_USE_FILE})
- Added new macro ROOT_ADD_TEST(...) to add tests into the project and
  a new script RootTestDrover.cmake 
- Added a new option 'testing' to enable CTest tests.
- Moved CPack setting to its own file in cmake/modules/RootCPack.make
- Moved CTest settings to its own file in cmake/modules/RootCTest.cmake
- Simplified the StandaloneBuild.cmake to make use of the new ROOTConfig.cmake
- Added the tests available in /test directory
