Fix issue #10060 - add APPEND arg to ctest_start command.

If APPEND is given to ctest_start, it will read the tag from the current existing Testing/TAG file rather than creating a new one based on the current time stamp. This allows a developer to run several dashboard scripts in a row, all of which will share the same tag/stamp/buildid when they finally get submitted to CDash. Now you can split the running of build phases and test phases for the same dashboard row into multiple scripts.
