Title: Don't remove subscription notifications for email replies

Fixes #8.

There were two options to fix this:
1. spoof the required `$_POST['bbp_topic_subscription']` value to have subscriptions persist
1. call `bbp_add_user_subscription()` directly

I decided on the second, though the first might be more robust if bbPress depends on it in other places.

I also didn't include any of the conditional logic bbPress uses before calling `bbp_add_user_subscription()` because if a user is replying via email, then they've obviously subscribed via email.
