rate poll: Commit early

We do not want to lose the user's vote under any circumstances. Therefore, we should commit it as early as possible, in particular before sending events. Note that the events still get commited, since event.emit calls commit on its own.
Makek massmessage footer optional.

Currently, every message has the unsubscription footer. That's fine (even required) in open communities, but out of place if there is some kind of central user management (say, in a company), and if non-technical users may not even be aware we're using adhocracy as a newsletter service.
This commit therefore allows users with global.admin permissions to suppress the footer.
