COMP: Update Slicer, CTK and BRAINSTools to fix outdated builds on VS2012

High-level build did not build external projects in VS2012. The BUILD_ALWAYS flag is a relatively new CMake feature (added in 3.1), therefore the following workaround was added into SuperBuild.cmake:

This custom external project step forces the build and later

steps to run whenever a top level build is done...

ExternalProject_Add_Step(${proj} forcebuild
COMMAND ${CMAKE_COMMAND} -E remove
${CMAKE_CURRENT_BINARY_DIR}/Slicer-prefix/src/Slicer-stamp/Slicer-build
COMMENT "Forcing build step for '${proj}'"
DEPENDEES build
ALWAYS 1
)

This does not work with Visual Studio, where the stamp file is in Debug/Release/etc. subdirectory:
${CMAKE_CURRENT_BINARY_DIR}/Slicer-prefix/src/Slicer-stamp/${CMAKE_CFG_INTDIR}/Slicer-build
