[1.28.05] Changed names of voice variant files (espeak-data/voices/!v).

Moves "wisper" and "croak" into voices/!v.
Voice variants can now be specified as  en+wisper, en+f2 (for female 2), etc.
espeak --voices=variant  lists the voice variants.
Moves some lines from speech.h into other header files.
Possible fix for data version check on big-endian.
Fixed crash error iin LoadConfig().
Fixed crash in espeakedit: press Tab in enpty Prosody window.
