Hi,

I recently began using the org-notify package, and I would like to pass
the :urgency flag to `notifications-notify' occasionally. This small
patch passes the :urgency key from the org-notify configuration on to
`notitifications-notify'.

For example, after this patch, you can:

(org-notify-add 'test-notifications
'(:time "10m" :period "1m" :actions -notify/window :urgency critical))

And get notifications labeled as critical in that way.

Eventually, I would like to write an alert
(https://github.com/jwiegley/alert) backend for org-notify, would that
be suitable for inclusion in the core package?

Thanks,
-Jay
