Hi!

I've been doing some changes, but they are taking too long. So I'm releasing this version with a couple bug fixes and features. More features in future release.

-Bug fixes: Fixed a bug that caused settings to reset when opening new image.
                 Fixed a bug that caused program to crash randomly when opening and closing images.

-New features: Now you can open multiple images at once in the file dialog! Just select all images and press open.
                        Now you can export all normal maps at once! Just click "Export All" button. Every normal map will be saved in the same directory than the original texture, with "_n" prefix added.

Please, give me your feedback! It's important so i can improve the software. Give me your opinions, your suggestions, tell me if the program worked or not.

Thanks!
