Dear Maintainer,

When listening to podcasts with audacious, sometimes 2x speed is not
enough.  I find 2.4x to 3.0x is listenable, depending on the content.
The following patch increases both the granularity of change possible
and the maximum range of the speed/pitch shift plugin, as well as the
frequency for a smoother speedup sound.  This patch, written for
audacious-plugins 4.4.2 makes it possible to listen to more podcasts,
faster. Especially with a large amount of coffee.
