I was finding many problems with slow lagging notifications to some devices due to the time in sending emails or Twilio messages.
This refactor of the notifications code in the webapp will ensure all notifications that have slow IO intensive process run in parallel.
This will add a small delay to each delivery but prevent stalling out of the web interface or other notifications due to one notification that is slow.
It will require me to make a new image or if you want the feature to manually add a new package. AFAIK this will not cause any issues with future porting to Python 3.
