Added: Analysis panel which shows the calculated frequency response of the filters for the selected device and channel.

Improved: GUIs of GraphicEQ and Copy command can now be resized
Improved: GraphicEQ GUI can now be zoomed separately in X and Y direction using mouse wheel on rulers. Also now shows values at mouse position.
Fixed: Original APO was not released when E-APO was shutting down, leading to a memory leak.
