TTS encoders: allow volume range between 0.0 and 2.0.

SAPI only allowed values from 1.0 to 10.0, making it impossible to turn down
the volume of the voice. Increasing the volume by a factor of 10.0 is nothing
that is likely to be useful, so change the upper limit to 2.0 and decrease the
lower limit to 0.0.

Lame allowed values from 0.0 to 1.0, making it impossible to increase the
volume of the voice. Change the upper limit to 2.0 as well.
