mbrola: Fix portuguese and french voices priorities
- We want to use br* voices in priority for Brazilian Portugues, but not
for general Portuguese.
- We want to use ca* and Belgian voices for Canadian and Belgian French,
but rather not for general French.
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.
