[SR-Users] Dialog module - shared state

[Charles Chance]

Hi Daniel,

Yes, dmq is the clear way forward once it's working. Is it a lot of work to
get going again? For it to be really useful, I would imagine other modules
will need to make use of it from within their code, rather than the user
trying to do stuff in the config. I may take a look and see how far along
it is.

The others all seem to hinge around dialog:start and dialog:end event
routes, but we really need to replicate info about early dialogs too. So I
think we'll have to send some notifications from the other routes as well.

Anyway, thanks again,

Charles
