Introduction of recycle bin and marking of photos

Photos are no longer deleted directly but are now moved to the recycle bin first. This saves time when sorting photos, as you no longer need to confirm each deletion individually, but only when you want to empty the recycle bin. This is implemented using the "rejected" rating in the metadata, making it compatible with other programs like ACDSee.

We have also implemented the counterpart, the marking of photos. In addition to the rating stars in the photo view, you can now mark a photo by setting a checkmark. This, like everything in the Photo Organizer, is also saved in the metadata and can be exchanged with other tools.

We hope you like these changes and look forward to your feedback. :)
