EXIF Fixup

Update EXIF DateTime values based on file name generated by Camera app.

This application contains a service that monitors the DCIM/Camera folder and alters the EXIF data for the files captured with default Camera application.

The service starts automatically on boot.

You can also fix existing files using “Fix existing photos” menu item.

Why this is needed:

A number of Android phones have a bug that sets the EXIF date and time to 2002-12-08 12:00:00. It does not look broken initially because the Gallery application sorts the files based on the last modification date. Once the photos are imported into any application that understands EXIF tags, all the files will be grouped into an event that happened at noon on December 8, 2002.

This date is hardcoded into libcamera.so and the latter is closed-source.
