Title metadata not being written to ORF files
Mandatory: Shotwell version the issue was seen with
The expected behaviour
When "Write tags, titles and other metadata to photo files" is turned on, metadata should be written into the file.
What was actually happening
Metadata is correctly written to jpeg files, but not to ORF files.
Steps to reproduce the issue
Give a jpeg image a title. View the metadata with exiftool or exiv2. The title appears in the metadata. Give an ORF file a title. View the metadata with exiftool or exiv2. The title doesn't appear in the metadata.
