Nightly test changes:

- Put the old tree in valgrind-old/ and the new one in valgrind-new/,
  instead of using valgrind/ for both.  That way, the old tree is still
  present after running the tests, so it can be inspected for problems.

  This required changing how ABT_RUN_REGTEST worked -- it no longer should
  change directories itself -- but I think Bart's machine is the only one
  using that and I updated the .conf file accordingly.

- Change some variable names -- only use the "ABT_" prefix for variables
  defined in the .conf files, and use $DIR and $TAG to match the README.txt.
