[Shotwell] Option to save changes.

[Daniel Leining]

Hi, I've recently began using shotwell to manage the photos on my
computer. I like it very much, however, I have one suggestion. When I
crop my pictures, or use the "Enhance" button, I'd like an option to
save the changes. I know you can export the pictures, but that's a pain.
Theres 2 ways I'd like to suggest doing this.

1. Add an option to preferences to make the changes final.
    My concern with this is making the "Revert to Original" option still
work. I guess a way around this would be to keep the original picture in
a hidden folder and have the program access it if needed.

2. Add an option in the application's menus that would allow you to save
all changes. This could pop up a dialogue alerting you that there is no
way to undo the changes, or it could keep the original, as suggested for
the first way.

Either of these would make the program MUCH better for me, and probably
a few other people.
Let me know what you think.

Thanks,
Daniel Leining
