Keep the original voice variant across SSML xml:lang changes.

Use the original language sub-type (eg. en-sc) when SSML xml:lang changes to a compatible language.

SSML <emphasis>, increase volume for "strong" and "x-strong".

Fix bug where </emphasis> was ignored at end of clause.

Fix: $dot attribute was ignored for multi-word entries in *_list files.
