Small program which uses rawtherapee to convert raw files to jpgs.

Features include:

1. Process a given directory recursively and mirror it's structure under the given output path. That way you get the same directory structure for your converted raw files.
2. Override already converted raw files ONLY if there is a pp3 given which contains different settings than the ones the existing jpg has been created with. To make this possible the program always saves the pp3 file together with the jpg file in the output path.
3. The program will use the pp3 given with the viewed raw file to convert it.
4. If there's a default pp3 given and the viewed raw file has no pp3 file attached the program will use that default one to convert the raw file.
5. If there's no default pp3 given and the viewed raw file has no pp3 file attached the program will use the one that is set as default within the rawtherapee context.
6. Log each decided action to stdout so the user knows what's going on.
7. A dry run is possible, doing nothing but logging what would be done.

This is exactly what the author needs for realising a smooth raw conversion process. The files will get converted to a raspberry pi and distributed within LAN from there. Maybe it's useful for anyone else.

1. Respect current pp3 Resize settings instead of simply overriding them.
2. Don't override the source pp3 file when in dlna mode.
3. Relax the src pp3 target pp3 equals function. If they differ only by dlna overrides, ignore that.
