Adds links for the compat un/subscribe action to the support view.

Filters `get_the_term` to provide a safe redirect for the subscription action.

Subscription links will generate a compat term and save it if needed; newly added plugins or themes will have empty support forums/reviews and will not have a term in the database already.

Moves term insert on new topics from `bbp_new_topic_post_extras` to priority 9 of `bbp_new_topic`. This allows us to set the compat terms (if any) for the new topic before term subscriptions checks terms on the topic.</pre>
