+ Added color curves dialog
+ Fixed plugin recognition routines. Variations, which were already built-in were loaded anyway which lead to an "Access Violation" storm in the editor. Thanks again morphapoph for tracking the origin of the problem in such a masterful way!
The color curves dialog is very simple and straight forward. Works like the one in Photoshop. Or Chaotica. Or GIMP...and it's not perfect. It's a new feature and maybe a bit bugged. But we'll see how much better it gets over time
