Feature Request: export contents listing as text

[gingerbeardman]

I'd like the ability to export file listing for cataloguing purposes.

I don't mind trying to hack on this one myself if you could provide some initial guidance? Best function to hook, etc.

Maybe I'd start with outputting the filenames to the Debug console and go from there?

Possible locations:

• next to the Extract data option at root node context menu
• a button on the Volume information > Catalog file window
• as an item in the File or Tools menu
• as a command line option

Alternatively, an option to run the app in a headless mode would perhaps be better so that it can be run on the command line with no user interaction needed. See #22
