.dorico file hardcodes full path of video file rather than relative path

I notice that the .dorico file uses the full path of a video file attached to a flow. This seems improper, when the video file is Attached from the same directory or subdirectory of the .dorico file. The .dorico file should use the relative path, not the absolute path. Using full path could be considered a security issue.

Additionally, the UI for Attaching a video file also needs improvement. The ‘Attach…’ UI should default to browsing for the video file starting in the same directory as the .dorico file. Instead, it defaults to the Dorico templates folder.
