A file can be in multiple albums, but the same file can't be in the same album multiple times. This can happen in multiple cases, for instance:
- If one of the mapping for the album contains "/"
- If a file is stored under "sub/file.jpg", one of the mapping is "%path" and the other is "sub"
Fixes#220
- %path expands to the path of the photo/video
- %keywords expands to the IPTC keywords of the photo
- {format} expands to the photo's EXIF date, e.g. {YYYY MM}
