Move Announcement Settings to Global Email Notifications

[#1]

Currently a user can select their announcement settings from the Announcement page, which is fine. But my users would never think to go here or take the time to do it, and 99.9% of these are not relevant to my users. As an admin, I really wish these settings were options in the global email notifications area in Setup so I can set these! Would like to see these settings move from their current location to email notifications area from their profile (and from Setup for admins). In setup, I have announcement off for my users because they are not relevant, but I've wanted to use this features for my own WF-related announcements.
