This is basically like 6 stories in one branch, so... yeah. But here is the original story:
https://www.pivotaltracker.com/story/show/187044314

What this PR does:

Summary of relevant changes:

1. add the TO field to the email template and integrate with the backend. This required adding a "to" column to the EmailTemplate database, updating the view files, and changing the logic for how emails are sent out. To see changes reflected, run "rails db:migrate". See the corresponding RSpec test with Barney the purple dinosaur which verifies that the changes work.

2. Fix the email template CRUD actions. There were two circumstances where if you entered invalid information when editing the email template or creating a new email template it would simply crash the app. So, I fixed it so that instead it displays flash messages. See the new Cucumber tests.

This pull request fixes|implements (pick one...) ______.

@ArushC Looks good to me overall. Nice job.

The only concern I have is about the PR granularity, but it should be fine for this time. We can check with Micheal at next time's meeting.
