Send an email on task completion

[mukul-mehta]

If an email flag is set, send an email to notify task completion. Will be useful on headless sessions and tasks running on servers.

We could use Mailutils or cURL using SMTP to handle mailing.

This is a good implementation for mailing which a friend had implemented: https://github.com/Vipul999ujawane/Gru_Noti-FIRE

Currently, I'm not actively developing this tool so this issue is up for grabs.
