Issue 2035: Add email notifier with per show notification lists

[Slugger]

This patch provides email notifications, with support for TLS and SMTP AUTH. It provides the regular notifications on snatch and download. It provides the ability to give a list of "global" emails, which receive notifications for all shows and it also allows configuration of email notification lists on a per show basis. This addresses Google Code issue 2035. Screenshot attached to that issue.

Tested using Gmail's SMTP server (TLS + SMTP AUTH) and my ISP's SMTP server (no TLS, no AUTH). Both worked as expected.

Tested on my (relatively old) Linux VM (Ubuntu) using python 2.6.5 and Cheetah 2.0.1. Also tested on WinXP using python 2.7.3 and Cheetah 2.4.4.

Changes are pretty standard except I added a new column to the tv_shows table, which stores the list of email addresses configured for each show.

I just tested this with my gmail account and it works great! Please merge this!

new code needs to be based off the development branch, not master

[Slugger]

If I become inspired again, I'll redo this enhancement against development branch. Seems unlikely at this point, but you never know.

Is email notification going to be implemented? really needing this:)

[xombiemp]

I created a new pull request for this against the development branch. https://github.com/midgetspy/Sick-Beard/pull/569

[RobinMM]

Much thanks, looking forward to it. couch potato also finally has email notification.

why not just use sab's email notification ability?

[xombiemp]

I don't use sab. I use rutorrent.

i am using sabs mail notifications, but things are changing.. So want couch (it is possible with couch) and sickbeard only send mail upon complete download.
