ctest: Add --rerun-failed option

Add a new command line argument to ctest.  This allows users to
rerun tests that failed during the previous call to ctest.  This
is accomplished by analyzing the most recently modified file named
"^LastTestsFailed*" in the Testing/Temporary subdirectory of the
project's binary directory.
