Fixed bug where SSML voice change didn't remember an initially specified Klatt variant.

Removed some unused variables and redundant initializations.

Patch to fix a spike from Klatt function setzeroabc()

Amplitude changes now apply also to mbrola voices.

"voicing" attribute is now used in mbrola voice files to set the voice loudness.

SSML commands such as <mark> and <prosody> were ignored if they were inside a multiword group (defined in *_list).  This is now fixed so that the command is processed at the end of the group.
