Dexter LD-V1000 emulation improved

Thanks to all of our efforts testing Cobra Command conversion, we've discovered a defect in Dexter's LD-V1000 code and I just checked in a verified fix.  The defect caused cobra command to lock up during death scenes when used with Dexter.

So I am going to update Dexter's "status" to show that Cobra Command is now tested and working with Dexter (in LD-V1000 mode).
