Feature for alerts to work like Google Calendar/Outlook alerts

[codygman]

Right now org-alert pops up notifications for each item in the org-agenda. I think it could be useful to notify when a scheduled item is coming up, maybe 15m by default but also looks for one or more REMINDERN properties.

It would also be convenient for my use case to have an alert on end time so I know when I should be wrapping up a task or already have finished it.

Thoughts?

Having a feature to set the number of minutes before a notification for a scheduled/deadlined item is planned (hopefully get it done in the next few days). Before I can do that I plan on cleaning up the codebase significantly by making a polyfill for the org-map-entries function in #17 for users of org < 9.

Once this is done then it will become trivial to modify the behaviour of notifications to add the functionality you want.

I meant to comment on this earlier, but I think the package now has at least part of this feature. I've left it open because I would still like to implement your idea about the REMINDERN properties, but the notification cutoff part should work now.

Finally got around to the REMINDERN part in bddb342.
