Forum email notifications

[wabscale]

Here is the most delicate part of the whole thing. Email notifications are a dangerous thing. If you make a small mistake you can accidentially send emails off to hundreds of people if you are not careful. No pressure lol

We will need to have a few boolean values added to the user table for things like:

• is_new_post_notification_enabled # For each new post
• is_comment_notification_enabled # For followup comments
• is_instructor_post_notification_enabled # For when a TA/Professor posts

We can then send emails in RPC jobs. Nothing fancy needed, we already have the logic for sending emails. We will need email templates written for the different types of events too. We can follow the existing models:
