[DECtalk] It's time to bust some DECtalk myths

[Blake Roberts]

I agree with Josh in requesting that Jake create a SAPI5 version of 
Dectalk 4.60 if possible. He has a very valid point that future updates 
to NVDA could break the present add-on. Also, with SAPI we can use 
DECTalk outside of NVDA.
