Investigate alternative storage solutions to current dotstop.dot implementation

The dot file isn't very compatible as a storage format and so we should look at alternatives.

Some key features that I think are important to consider:

• Enable SHA storage for references/fallacies... (enable traceability of changes)
• Reduce merge conflicts due to adjacent item changes (currently they're line after line, which causes unnecessary merge conflicts)
• Enable separation into separate files (reduce unnecessary rebase approval resets due to patch-id)
