v0.9.4

Changes to Equalizer which allow for construction without the build() classmethod.

Added name parameters to the build() classmethod and Equalizer constructor to allow setting a custom name.

Added a name property to Equalizer. Setting the name should be done by constrcutor or the build() classmethod

Added __str__ and __repr__ to Equalizer.

Fixed a bug where set_eq was setting a blank Equalizer class on the player.
