this module is the start of extracting some more generalised tools for threads in scuttlebutt
Features:
- subject
- preview
- attachements
- preview attachments option
- drag and drop
More generally:
- decouple from patchcorePublish
- extract an attachment feature
- go refactor patch-inbox (which I've stollen a lot of this from) to use the results of this
- consider extracting some of the common tools in lib into modules
