A new version of MTmyVFP (True VFP multi-threading) using Calvin Hsia's
latest MT class including a few tweaks:

There's still room for improvement, though. Instead of a count-down while
the thread(s) is going, a nice Progress bar like the one in VFPX could
probably be used. Also, it probably wouldn't take much to make this backward
compatible to VFP7. However I'll leave these improvements to others.
