Genetic Algorithm, Cellular Automaton (update 1.20)

This is the last update before final release. I hope that you like it!

This update includes:

-Genetic algorithm for color evolution. Use your colors as first population and evolve them removing unwanted ones.

-Cellular automaton use your colors as seed for first population of cellular automaton. Change rules along the way.

-Multiple images can be loaded now. Each one of them can have color replacement turned on.

-Added transparency slider which affects all dialog windows and menus.

- Added help tips. Use F1 or question mark in the top right of the screen to display it (Unfortunately    works only on PC. On Mac help files    must be accessed manually).

-Color extraction can't be executed multiple times now. One process must complete   its task before another can be triggered.

-Fixed project loading / saving issues.

Thank you for the support and suggestions !!!
