- turned off _debug framework support in tests since we now capture a lot more

  in log validation.
- Added GTM_SUPPORT_GC for controlling the inclusion of GC related code.
- If you are using GTMUnitTestDevLog, it also tries to capture logs from
  NSAssert.
- Added GTM_FOREACH_OBJECT/GTM_FOREACH_KEY that uses NSEnumerator and
  objectEnumerator/keyEnumerator on 10.4, but on 10.5+/iPhone uses
  FastEnumeration.
- GTMNSWorkspace+Running gives a variety of ways of determining the attributes
  of running processes.
