Separate default quality setting for encoders.

Instead of having a global quality setting for the encoder make the encoder
provide its default value by itself. Fixes the libmp3lame encoder using an
unsuitable value since the range differs greatly between the encoders.

Centralize reading the configuration values for rbspeex. The values are stored
in member variables, so it's not necessary to read them multiple times.
