This needs a much better way of working.

Only include the first line. Reverse order of commits so they're
chronological.

Have one route for all hooks that delegates to the appropriate
service. Services yield events that are then actioned somehow
(for now in a big ugly method).

This will need to change when the config is rethought a little.

This allows the IDE to run it as a flask application, rather
than just executing script fully.

Doesn't really do much of use yet.
