Implement tournament broadcasts

User Story

As a TO, I want to be able to broadcast a message to all players by email.

Functional Requirements

• TO can write a message. On send, the message is emailed to all players.

Implementation Details

This is a stub of a future feature. Whatever implementation is chosen, it should be adaptable in the future for push notifications, in app-notifications, and possibly even conversations. This means it would likely be wise create 1 DB record per message copy with a read status, etc.

Alternatively, it could be 1 message, without recipients, and 'replies' could be messages with a parentId field pointing to the original message's _id.

Then the email portion would simply be a check that if a tournament has a new message added, by the TO, email all players a copy of that message.

This could eventually be expanded into a Reddit-style discussion thread per tournament.
